Following the successful completion of Phase I upgrades during LHC Long Shutdown 2, the ATLAS detector has been operational since 2022 with various implemented upgrades. The most important and challenging upgrade is in the Muon Spectrometer, where the replacement of the two inner forward muon stations with the New Small Wheels (NSW) system introduces two novel detector technologies: small...
To improve the muon tracking and triggering capability of the most forward part of its muon spectrometer CMS has decided to install, for the High Luminosity LHC, three stations of large (> 1 m long) Triple-GEM detectors. These stations are named GE1/1, GE2/1 and ME0, respectively. While GE1/1 and GE2/1 will work jointly with the existing CMS Cathode Strip Chambers (CSC) in the pseudo-rapidity...
In anticipation of the High Luminosity LHC, an extensive upgrade is underway for the CMS Muon system to ensure its optimal performance in muon triggering and reconstruction. The indispensable role of Resistive Plate Chambers (RPC) as dedicated muon detectors stems from their exceptional timing resolution. To meet the requirements of Phase-II of the LHC, the RPC system will be expanded up to...
We will present a new type of MPGD: micro-resistive groove (μRGroove). The μRGroove is a single-stage MPGD, it has the similar stack structure with μRWELL but a groove amplification pattern. The μRGroove is almost compatible with all the techniques developed for μRWELL, for example, it can be directly make the PEP fast grounding lines for high rate applications and the dead area is less than...
The challenges posed by the forthcoming High-Energy Physics experiments, necessitate the development of particle detection technologies that are easily engineered and compatible with industrial-scale production. The micro-RWELL, a single-amplification stage resistive MPGD based on sequential build-up technology, effectively meets these demands. In this contribution, we provide an overview of...
In order to accurately establish leptonic CP-violation the T2K collaboration planned to upgrade both the neutrino beam line, by doubling its intensity and the ND280 Near Detector, for collecting neutrino interactions within full phase-space acceptance. The innovative concept of this neutrino detection system consists in combining a fine-grained fully active target (Super-Fine-Grained Detector)...
The PICOSEC-Micromegas (PICOSEC-MM) detector is a novel gaseous detector aiming to offer precise timing resolution in experimental measurements. The main idea is to eliminate the time jitter produced by charged particles in ionization gaps by exploiting extreme UV Cherenkov light emitted in a crystal, which is then detected by Micromegas photodetector using an appropriate photocathode. The...
The MPGD team at CEA Saclay has been involved in designing, producing, validating, and, operating Micromegas detectors for the current and next generation of experiments in many different domains of physics. The detectors are now operating in the largest physics experiments including ATLAS-NSW at CERN, CLAS12 at Jefferson lab, and, sPHENIX at BNL. Early results and status of Micromegas in the...
In the last years, the particle detector community faced a new challenge: how to convert existing and future gaseous detectors in more eco-friendly ones. Indeed, several detectors make use of greenhouse gases (GHGs) since they allow achieving excellent performance and long-term stability. With a growing concern on climate change and future restrictions, it is fundamental to look for solutions...
Many dark matter experiments are exploiting the Migdal effect, a rare atomic process, to improve sensitivity to low-mass WIMP-like dark matter candidates. However, this process is yet to be directly observed in nuclear scattering. The MIGDAL experiment aims to make the first unambiguous measurement of the Migdal effect in nuclear scattering. A low-pressure optical Time Projection Chamber is...
