Resistive Micromegas detectors have proven, over the years, to be a reliable detector technology. This presentation will report on further improvements and developments of such detectors for robust and stable operations. The ongoing project focuses on the optimisation of the design with small readout elements, employing pads, and of the spark protection system. Optimal layouts have reached...
The novel G-RWELL Micro Pattern Gaseous Detector (MPGD) is a hybrid configuration that combines two technologies - Gas Electron Multiplier (GEM) and μ-RWELL - to achieve gas gains above $10^4$. This makes it a cutting-edge solution for high-precision tracking applications.
The higher gas gain is reached thanks to the inclusion of a single GEM layer for signal pre-amplification, and it...
AMBER (NA66) is a fixed-target experiment at M2 beam line of the SPS, devoted to various fundamental QCD measurements. For this new apparatus we are designing together with the CERN MPT workshop both a ~1.2x0.5 $m^2$ bulk resistive MICRO-MEsh GAseous Structure (Micromegas) detector and a new custom 64 channel fully digital front-end ASIC ToRA (Torino Readout for AMBER) for timing and energy...
The Imaging X-ray Polarimetry Explorer (IXPE) represents the current state-of-the-art of astrophysical X-ray polarimetry. This mission (collaboration NASA and ASI) has been launched on December 9th 2021 and it can measure the linear polarization of different astrophysical sources over the photon energy range 2-8 keV. The core of IXPE Detector Unit and future X-ray polarimetry missions is the...
Gas Electron Multipliers (GEMs) are crucial for high-resolution X-ray polarimetry, enabling precise measurements in astrophysical missions like IXPE, Polarlight, and the upcoming eXTP telescope. While the IXPE collaboration has refined Gas Pixel Detector (GPD) technology using conventional GEM fabrication methods such as wet-etching and laser drilling, further optimization of hole patterning...
We present the design, development, and initial performance of a large-volume, wide field-of-view Time Projection Chamber (TPC) tailored for X-ray polarimetry. The instrument employs a triple-GEM detector with an optical readout system, using a scientific CMOS (sCMOS) camera to capture the secondary scintillation light produced during gas amplification. Initially optimized for directional Dark...
The identification and discrimination of electronic and nuclear recoil events at low energy thresholds are significant challenges in contemporary dark matter direct detection experiments. Gaseous Time Projection Chambers (TPCs) with optical readout offer a promising and innovative solution in this context. As a result of the high granularity and sensitivity of advanced scientific CMOS (sCMOS)...
The MEGII experiment at the Paul Scherrer Institute (PSI) has set the best upper limit in the world on the branching ratio of the Charged Lepton Flavor Violating (CLFV) decay $\mu^+ \rightarrow e^+ \gamma$, equal to $\mathcal{B}(\mu^{+} \rightarrow e^+ \gamma)<3.1\times 10^{-13} \text{ (90% confidence level)}$. If this decay is observed experimentally it would indicate evidence of New Physics...
The challenges posed by upcoming high-energy physics experiments necessitate the development of advanced particle detection technologies that offer exceptional tracking and timing performance while ensuring robustness in harsh environments.
In this contribution, we present a summary of the R&D efforts on $\mu$-RWELL technology, a single-amplification-stage resistive Micro-Pattern Gaseous...
