        <description><![CDATA[The integration of resistive materials has fundamentally advanced Micro-Pattern Gaseous Detector (MPGD) technology, enabling robust, high-gain operation essential for modern particle physics experiments. Diamond-Like Carbon (DLC) has emerged as a superior material for this purpose due to its uniquely tunable electrical, mechanical, and chemical properties. This article provides a comprehensive review of the development, fabrication, and application of DLC-based resistive coatings for MPGDs, with a focus on work conducted by the University of Science and Technology of China MPGD group. We detail the material fundamentals of DLC, systematically introduce magnetron sputtering as the core deposition methodology, and analyze the critical relationship between coating properties—such as resistivity, uniformity, adhesion, and stability—and final detector performance. A thorough examination of specific detector architectures (μ-RWELL, μRGroove, THGEMs, RWELL, Picosecond Micromegas) demonstrates the transformative impact of DLC. Finally, we summarized the outstanding technical challenges and present a perspective on future research directions aimed at scaling this technology for next-generation experiments.]]></description>

        <description><![CDATA[Resistive electrodes are a critical component of Micro-Pattern Gaseous Detectors (MPGDs) for dealing with discharges. This study introduces an advanced approach using germanium (Ge) thin films as resistive anodes in MPGDs. The Ge films are fabricated via vacuum thermal evaporation, which enables the production of large-area and uniform on rigid substrates. Characterization confirms the film stability for over 700 days, which is attributed to surface passivation. It also reveals an inverse correlation between resistivity and temperature. Micromegas detectors equipped with Ge resistive anodes achieve high gain, low spark rate and high rate capability. These results validate Ge-film resistive anodes as a reliable and scalable technology for improving the performance and stability of MPGDs in future particle physics experiments.]]></description>

        <description><![CDATA[The ARIADNE programme is focused on the development of a scalable optical readout system for use in future ktonne LAr neutrino experiments, providing high tracking capability and low energy thresholds. Following demonstration at the 1 tonne scale (ARIADNE detector), a 20 tonne experiment has been performed at the CERN Neutrino Platform (ARIADNE+) to test scalability for integration into colossal future experiments such as those planned within the DUNE programme. This paper details the design, construction and performance of a 2.3 × 2.3 m light readout plane (LRP), which contained the largest glass THGEM array ever constructed. Four Timepix3 cameras were mounted externally to image the secondary scintillation light produced within the THGEM holes; three cameras operated with a visible image intensifier, and one with a VUV sensitive intensifier coupled to a custom magnesium fluoride lens. The Timepix3 data are natively zero suppressed, and with the 1.6 ns timing resolution, straightforward 3D event reconstruction is possible. A gallery of reconstructed LAr interactions is presented. Energy resolution and calibration were determined using cosmic muons. The energy resolution was found to be approximately 11% for the presented dataset. An outlook on the next steps for this work is given.]]></description>

        <description><![CDATA[Semiconductor radiation detectors play a crucial role in scientific research and technological applications, with materials typically categorized as low- or high-Z depending on their atomic numbers and densities. This distinction is not strictly defined because the selection of materials depends on the specific application and the energy range. Low-Z semiconductors such as diamond, silicon (Si), selenium (Se), and silicon carbide (SiC) are widely used in X-ray and charged particle detection due to their excellent charge transport properties and radiation hardness. High-Z semiconductors, including germanium (Ge) and compound materials such as cadmium telluride (CdTe), cadmium zinc telluride (CdZnTe or CZT), and emerging lead halide perovskites (most promising is CsPbBr3), offer absorption efficiency in the hard X-ray and gamma-ray regions comparable to CZT. These materials enable advancements in diverse fields, including biology, astrophysics, medical imaging, and industrial inspection. At Brookhaven National Laboratory (BNL), the Instrumentation Department is at the forefront of developing cutting-edge semiconductor detector technologies to address the evolving needs of fundamental and applied research. The projects cover the entire development cycle, from the investigation of new materials and optimization of detector architectures to the design of low-noise readout electronics and signal processing techniques. The ongoing research projects focus on next-generation detection systems that improve sensitivity, energy resolution, and robustness for a wide range of applications. The continuous demand for versatile and high-performance detector systems drives research in multiple directions with emphasis on advancing detector integration within complex experimental requirements, ensuring seamless compatibility with large-scale scientific facilities, and developing scalable and cost-effective fabrication techniques. The combination of novel materials, innovative detector designs, and state-of-the-art readout electronics paves the way for next-generation semiconductor detectors with unprecedented performance. In this work, we present an overview of our recent advances in semiconductor detectors and their applications.]]></description>

        <description><![CDATA[We have developed a comprehensive methodology to measure electron transport and electroluminescence parameters in xenon-based gaseous detectors using photosensor waveform analysis. Our approach integrates measurements of the Fano factor, electroluminescence fluctuations (Q-factor), scintillation probability, electron drift velocity, diffusion, and attachment coefficients into a unified experimental framework, with particular focus on the effects of molecular additives. Using a driftless Gas Proportional Scintillation Counter and advanced event-depth analysis, we achieved an energy resolution of (7.42 ± 0.02)% FWHM with 5.9-keV X-rays, measured the Fano factor in pure xenon (0.222 ± 0.004), and characterized the impact of CF4, CH4, and CO2 additives on detector performance. Electron transport measurements showed good agreement with Magboltz simulations, validating our methodology. Through Monte Carlo modeling of electron loss mechanisms, we quantified how attachment affects both electroluminescence yield and statistical fluctuations, enabling separation of attachment effects from other yield-degradation mechanisms for accurate determination of scintillation probabilities. For applications requiring optimal position resolution through reduced diffusion, we compared three molecular additives at concentrations providing equivalent electron cloud spread (2.75 mm after 1 m drift): Xe-CF4 (0.015%) maintains near-100% scintillation probability but introduces significant electron attachment affecting energy resolution; Xe-CH4 (0.220%) reduces the scintillation probability by approximately 30% with minimal attachment; while Xe-CO2 (0.041%) combines reduced scintillation, moderate attachment, and VUV opacity. These findings provide a quantitative foundation for selecting optimal additives based on application-specific priorities in rare-event detection experiments.]]></description>

        <description><![CDATA[Xenon, in both its gaseous and liquid phase, offers excellent scintillation and ionization properties, making it an ideal target medium for rare event searches. We report on measurements performed with a dual-phase xenon time projection chamber sensitive to wavelengths from 170 nm to 1700 nm. In addition to the well-established ultraviolet (UV) scintillation, we observe coincident signals in a photomultiplier tube sensitive to infrared (IR) light, associated with both prompt scintillation in the liquid and electroluminescence in the gas. We study the time response of the IR signals and their dependence on the applied amplification field in the gas. Our findings support the observation of IR emission from electroluminescence and reveal a time response distinct from that previously reported for α-particles in gas. The results suggest that IR scintillation could provide enhanced signal identification and background rejection in future xenon-based detectors.]]></description>

        <description><![CDATA[A new concept of three-phase projection chamber filled with a collection of neon-nitrogen nanoclusters immersed in superfluid helium-4 is proposed for detection light dark matter particles with low masses (0.1–10 Gev/c2). Such a time projection chamber includes a drift region within aerogel-like structure formed by neon-nitrogen nanoclusters filled by superfluid helium and a gas phase camera where electroluminescence takes place. The proposed concept combines the promising properties of liquid helium as a target material for direct detection of light dark matter particles such as high quenching factor, substantial scintillation light, high radiopurity, and high impedance to external vibration noise with the new ones determined by the properties of solid neon and nitrogen. The presence of highly porous impurity structure will enhance the primary scintillation signal (S1) due to light emission stimulated by interactions of metastable He2 (a3Σu) molecules and He+ ions with impurity nanoclusters. The signal of electrons produced by the recoil event (S2) and drifting in external electric field will get additional input due to energy stored in nitrogen atoms stabilized on the nanoclusters’ surface.]]></description>

        <description><![CDATA[We present a review of the current experimental and theoretical understanding of electron transport in noble liquids. Special attention is given to recent measurements that coincide with the development of time projection chambers using liquid xenon and argon as detector media. To enable transparent benchmarking of simulations and to facilitate the comparison between early studies and modern time projection chamber data, we introduce a new open-access database of electron mobility and diffusion measurements. In particular, we emphasize the transition to large-scale detector designs which incorporate extended drift distances alongside improved purity control and field uniformity. On the theoretical side, we contrast empirical transport models with ab initio approaches, highlighting our recent efforts to incorporate low-energy, liquid-specific scattering phenomena, including coherent scattering, polarization screening, and bulk potential modifications. While elastic transport has seen substantial theoretical progress, inelastic processes in liquids, including ionization, exciton formation and interband transitions, remain poorly understood due to the lack of experimental cross sections and validated models. We also discuss the applications and challenges of modeling scintillation, doped and mixture-liquid targets, and gas–liquid interface behavior, all of which are critical for the design and optimization of next-generation detectors.]]></description>

        <description><![CDATA[We report new spectroscopic measurements of the near-infrared fluorescence band of electron-beam excited Xe2 excimers as a function of the gas density in several gaseous mixtures of different Xe concentrations at room temperature. We have used He, Ar, and N2 as buffer gases, with the Xe concentrations in the mixtures ranging from approximately 8% up to 80%. The investigated density range extends up to 10 times the density Nig of the ideal gas at standard temperature and pressure (Nig≈2.5×1025m−3). In all mixtures, we have observed that the wavelength of the centroid of the infrared excimer band is shifted toward longer wavelengths as the gas density is increased, in a manner similar to what was originally observed in pure Xe gas and an Ar–Xe mixture. The strength of the redshift depends on the Xe concentrations in the mixture and the nature of the buffer gas and is very well rationalized by taking into account both the classical dielectric screening effect due to the gaseous environment and the density-dependent quantum shift of the energy of the optically active electron in the Xe2 molecule, provided that the contributions of the two gaseous species in the mixture are weighted by applying the laws of ideal gaseous mixtures.]]></description>

        <description><![CDATA[Detection of photons with scintillating inorganic crystals in the high-energy range (>0.1 MeV) will be discussed, making a comparison with other available methods. Energy resolutions up to 2% at 662 keV and fast decay time of the order of 20 ns are within reach, with the introduction of Ce-doped crystals in place of alkali halide ones. Development is underway for the production of non-hygroscopic scintillating crystals, such as PrLuAg and Ce: GAAG. At the end of this review, examples of experimental devices based on scintillating inorganic crystals will be discussed. Practical hands-on experience is emphasized at the expense of a more comprehensive description of all available and possible options. Detectors’ construction details and consequences of the different choices will be discussed. Emphasis will be put on the LaBr3: Ce-based detectors that are the present “golden standard” in gamma ray spectroscopy. The focus of this review will be on photon detection in the high-energy region: mainly 0.1–2 MeV, including both gamma rays and high-energy X-rays, even if many considerations may be applied to the detection of low-energy X-rays.]]></description>

        <description><![CDATA[Positron Emission Tomography (PET) is a vital imaging technique extensively used for early cancer detection by visualizing metabolic processes in the body. While traditional PET systems use scintillation crystals like bismuth germanate (BGO) or lutetium oxyorthosilicate (LSO) to detect gamma rays, they have inherent energy and spatial resolution limitations. This paper proposes an advanced PET design using liquid xenon (LXe)-based detectors that integrate scintillation and ionization energy detection. Our PET detector design has a monolithic liquid xenon target of 5×5×5 cm3, from where scintillation light is detected by silicon photomultipliers (SiPMs) placed on one side of the target. The ionization is converted to field-enhanced electroluminescence in liquid xenon and detected by the same SiPMs. We use Monte Carlo simulations to optimize the configuration of the electric field and improve the light collection efficiency. Combining both detection modes, the proposed system aims to significantly improve the energy resolution to approximately 2% full width at half maximum (FWHM). Furthermore, machine learning models enhance position reconstruction accuracy with sub-millimeter horizontal and depth-of-interaction (DOI) resolutions. The results indicate that the LXe-based PET detector can achieve superior performance compared to current PET technologies, offering enhanced imaging accuracy with the potential for reduced doses of radioactive tracer.]]></description>

        <description><![CDATA[In nuclear and high-energy physics experiments, data acquisition systems handle vast amounts of data from thousands of detectors and electronic channels, often reaching hundreds of terabits per second. While modern field programmable gate arrays (FPGAs) offer high-speed transceivers capable of processing such data, a mismatch can arise: individual analog-to-digital converters (ADCs) process lower data rates than FPGA transceivers can efficiently handle. This inefficiency leads to unnecessary usage of more powerful and expensive FPGAs, thus increasing system costs. This paper addresses this issue by proposing a link aggregator method for ADC readout. The solution integrates five universal link aggregator devices within an FPGA mezzanine card (FMC) board, enabling 1-to-1, 2-to-1, 3-to-1, or 4-to-1 multiplexing. The system optimizes FPGA resource utilization with support for up to 40 optical or copper inputs (2.5 Gbps per link) and a 10-line aggregated output (10 Gbps max) via a Vita57.1 FMC connector. A low-cost, low-power FPGA manages the mezzanine board as an intelligent standalone device. This approach significantly reduces hardware requirements and enhances cost-efficiency in high-performance data acquisition systems.]]></description>

        <description><![CDATA[Optical readout of micro-pattern gaseous detectors relies on recording scintillation light emitted during electron avalanche multiplication with imaging sensors of high-granularity pixelated readout. It can be used in applications such as optical Time Projection Chambers for track reconstruction, low material budget beam monitoring or radiography, to name but a few. A good match between the scintillation light emission spectra and the spectral sensitivity of the recording devices is required to achieve high signal-to-noise ratios and ensure optimal acquisition parameters. Experimental requirements for operation at low or high pressures may have an impact on the scintillation spectra of gases commonly used for optical readout. We investigate the pressure dependence of scintillation light emission spectra of primary and secondary scintillation in the range of 1,000 mbar down to 25 mbar, in the wavelength range of 200 nm–800 nm. Primary scintillation spectra for different CF4-based mixtures are observed to be independent of pressure in the investigated range. A strong variation in the ratio of ultraviolet (UV) emission to visible (VIS) emission bands is observed as a function of pressure for secondary scintillation of CF4 and He/CF4 mixtures while for Ar/CF4 the overall light yield varies with an almost constant ratio between UV and VIS components. While the addition of low fractions of SF6 as electronegative drift gas does significantly lower the total light output, the shape of the emission spectra is not affected. The observed increase in relative UV emission for low pressure operation in CF4 and He/CF4 mixtures can guide the selection of optical readout devices or wavelength shifters for applications requiring low gas pressure operation.]]></description>

        <description><![CDATA[The efficient detection of low-energy X-rays at the keV level with the best possible energy resolution requires the application of silicon drift detectors (SDDs) and advanced application specific integrated circuits (ASICs). Their widespread use in material sciences, alongside dedicated basic science projects, has long been restricted to single, selected SDD elements working at low temperatures. This is because of the limits incurring in the quite elaborated planar technology production process and the need to reach very low leakage current levels, together with the need for highly specialized readout electronics. We describe, in this review work, the concrete outcomes of the efforts of the ReDSoX collaboration to develop high energy resolution detection systems working at near room temperature based on multi-pixel monolithic silicon drift detectors and custom-designed advanced readout electronics capable of dealing with high photon fluxes, developed for specific projects but suitable for a variety of applications.]]></description>

        <description><![CDATA[A new readout board for the digitization of the CMS (Compact Muon Solenoid) Muon Drift Tube (DT) chambers has been designed in order to cope with the increase of occupancy and trigger rates expected during operation under the foreseen luminosity in the HL-LHC (High Luminosity Large Hadron Collider). The board OBDT-theta (On-detector Board for Drift Tubes) can perform the time digitization and readout of the DT chamber signals measuring the z-coordinate (along the beam axis) of CMS. A total of 228 channels can be digitized with a time bin of 0.78 ns and full streaming of all the DT chamber signals can be made through optical links into the CMS counting room. There, the full detector information can be available to perform the trigger and event building logic. The different functionality of the OBDT-theta board has been verified and the overall architecture has been validated through specific tests. The OBDT-theta architecture and main functionality will be presented in this contribution, showing the suitability of the design for the expected functionality during the HL-LHC.]]></description>

        <description><![CDATA[This article summarizes the work performed by the authors in developing, during the last 2 years, several portable and wireless sensor systems that allowed the analysis of signals collected from multiple sensors based on the Internet of Things (IoT) in emergency contexts. These include fires and earthquakes, situations in which citizens suffer from poor health; participation of individuals in highly physical sports; or cases of materials used in buildings and other structures being subjected to high stress due to natural catastrophes other than the aforementioned fires and earthquakes. Novel material sensors like MXene paper or wallpaper-based ones used as fire detectors and operating remotely via Wi-Fi and LoRa are presented. Furthermore, a Wi-Fi communication system, physically connected to a commercial micro-controller, monitored the temperature and luminosity data. Other devices, such as IoT wireless systems operating under the LoRa protocol in the 868-MHz and 2.4-GHz band region and using RFM95 radio modules as possible risk advisers, are described. For the latter, the sensors integrated were triboelectric energy nanogenerators (TENGs). In addition, TENG smart masks with LoRa emitters were used and played an important role in risk mitigation. As novel systems, an STM32 LoRa board allowed monitoring of the health (heart rate and oxygen saturation) of athletes involved in combat sports, with a nano-IoT Arduino 33 chip being used for monitoring the electrical resistance change in some composite materials. Some of these developments, especially the previously mentioned one, can play an important role in structural health monitoring (SHM) by examining the mechanical properties during service operations in aviation or aerospace fields. A comparison of these systems allowed them to be classified according to the most fitting application.]]></description>

        <description><![CDATA[At the Large Hadron Collider, the vast amount of data from experiments demands not only sophisticated algorithms but also substantial computational power for efficient processing. This paper introduces hardware acceleration as an essential advancement for high-energy physics data analysis, focusing specifically on the application of High-Level Synthesis (HLS) to bridge the gap between complex software algorithms and their hardware implementation. We will explore how HLS facilitates the direct implementation of software algorithms into hardware platforms such as FPGAs, enhancing processing speeds and enabling real-time data analysis. This will be highlighted through the case study of a track-finding algorithm for muon reconstruction with the CMS experiment, demonstrating HLS’s role in translating computational tasks into high-speed, low-latency hardware solutions for particle detection and reconstruction. Key techniques in HLS, including parallel processing, pipelining, and memory optimization, will be discussed, illustrating how they contribute to the efficient acceleration of algorithms in high-energy physics. We will also cover design methodologies and iterative processes in HLS to optimize performance and resource utilization, alongside a brief mention of additional techniques like algorithm approximation and hardware/software co-design. In short, this paper will underscore the potential of hardware acceleration in high-energy physics research, emphasizing HLS as a powerful tool for physicists to enhance computational efficiency and foster groundbreaking discoveries.]]></description>

        <description><![CDATA[This paper discusses the microphysical simulation of interactions in liquid xenon, the active detector medium in many leading rare-event searches for new physics, and describes experimental observables useful for understanding detector performance. The scintillation and ionization yield distributions for signal and background are presented using the Noble Element Simulation Technique (NEST), a toolkit based on experimental data and simple empirical formulas, which mimic previous microphysics modeling but are guided by data. The NEST models for light and charge production as a function of the particle type, energy, and electric field are reviewed, along with models for energy resolution and final pulse areas. NEST is compared with other models or sets of models and validated against real data, with several specific examples drawn from XENON, ZEPLIN, LUX, LZ, PandaX, and table-top experiments used for calibrations.]]></description>
