Summary: Electrical discharges in gas detectors limit their performance, but the use of resistive materials has been found to be effective in mitigating this issue. This study compares electrical discharges in Thick-GEM-based WELL-type detectors with and without resistive elements, and introduces a new method for measuring discharges in resistive-detector configurations, providing evidence for the occurrence of discharges in the Resistive-Plate WELL detector configuration and the existence of the Raether limit.

Summary: Gas Electron Multiplier (GEM) detector is an advanced member of Micro Pattern Gas Detector (MPGD) group and widely used in High Energy Physics (HEP) experiments due to its high rate handling capability and spatial resolution. Investigation of the long-term stability is crucial for any tracking device used in HEP experiments. This article discusses the study on the long-term stability of a Single Mask (SM) triple GEM detector prototype by continuous irradiation using a 55Fe X-ray source.

Summary: This study investigates the efficiency, gain uniformity, and the effect of gas flow on the gain in a quad-GEM detector. The results show that the efficiency of the detector reaches approximately 95% at a specific voltage, and the gain uniformity fluctuates around 11.1% over the entire active area of the detector. It is also observed that different gas flow rates do not significantly affect the gain uniformity, but the overall gain starts to saturate at higher flow rates.

Summary: This study presents techniques for mass production of large-sized GEM foils for the CMS phase-2 upgrade by the Korean CMS group. The study focuses on the adoption of the double-mask technique in a foil production facility designed for mass production. It reports a polyimide wet etching technology that uses mono ethanolamine, which provides a safer working environment due to its lower inhalation toxicity compared to ethylene diamine. The study also covers the denaturation of the etchant over time and the process of retuning. Additionally, the research discusses R&D results on soldering surface mount resistors with hot air for faster production.

Summary: This paper presents a detailed investigation of the physics behind GEM charging-up and its effects on gain. Experiments were conducted on double and triple GEM setups, and the results were compared with those from single GEM setups. The study examined the increase in gain due to polarization of the GEM foil dielectric and the reduction in gain due to charge accumulation on the dielectric, under various field configurations and radiation intensities.

Summary: Germanium-on-silicon (Ge-on-Si) single photon avalanche diodes (SPADs) are proposed and demonstrated as high-performance waveguide coupled Ge-on-Si separate-absorption-charge-multiplication SPADs with three electric terminals. This SPAD exhibits high on-chip single photon detection efficiency and low dark count rates, making it suitable for applications in on-chip quantum communication and lidar. The proposed three-terminal SPAD enables high-yield fabrication and provides robust performance in operation.

Summary: This study characterizes the performance of Triple-GEM detectors in relation to their gas mixture composition using experimental measurements and computer simulations of the Triple-GEM electron amplification process. The correct proportion between the different gas mixture components is found to be crucial for stable detector operation, while common impurities such as N-2, O-2, and H2O can negatively impact their response reliability.

Summary: The CYGNO project aims to develop a high-resolution Time Projection Chamber with optical readout for directional dark matter searches and solar neutrino spectroscopy. Its unique features include 3D tracking capability provided by photomultipliers and scientific CMOS camera signals, along with a helium-fluorine-based gas mixture at atmospheric pressure amplified by gas electron multiplier structures. The upcoming underground installation of a 50-L detector at Laboratori Nazionali del Gran Sasso and the plans for a 1-m(3) experiment will be discussed, as well as the collaboration with the ERC consolidator grant project INITIUM for negative ion drift operation within the CYGNO 3D optical approach.

Summary: Thermal and cold neutron beamlines require detector systems with high efficiency, large active area, and good spatial resolution. This study presents a new design of Anger camera using silicon photomultipliers (SiPMs) instead of photomultiplier tubes (PMTs), offering better resolution, less distortion, and more compactness. The use of SiPMs also enables the camera to be used in strong magnetic fields, providing additional experimental capabilities.

Summary: This paper describes the mathematical foundation for analyzing vertical time-of-flight (TOF) measurements using ultracold neutrons (UCN). It enables the spectroscopy of UCN with kinetic energies below the neutron optical potential of the detector entrance window. The paper provides general treatment methods and transformation rules for converting vertical TOF spectra into other spectra of interest.

Summary: In this article, we report on the measurement of the time resolution of an LAPPD prototype using Cherenkov radiation emitted by high energy hadrons. Our approach has demonstrated the capability of measuring time resolutions as fine as 25-30 ps. The measured time resolution for single photoelectrons is about 80 ps r.m.s.

Summary: Self-supporting and Au backed Ag-107 targets have been fabricated using a combination of cold rolling and e-beam melting technique. The method is efficient, resulting in targets without significant material loss or major contamination. Various techniques have been used for thickness measurements and characterizations, and one of the fabricated targets has been successfully used in a nuclear physics experiment.

Summary: This paper presents measurements of the relative decrease of light output during irradiation of small plastic scintillator tiles read out by silicon photomultipliers. The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.

Summary: Resistive Plate Chamber detectors are widely used in current High Energy Physics experiments. However, efforts are being made to find eco-friendly gas alternatives to Tetrafluoroethane. The RPC EcoGas@GIF++ collaboration aims to improve RPC technology, evaluate the performance of RPCs with eco-friendly gas mixtures, and conduct aging tests.
