Description
High pressure gaseous argon time projection chambers (HPgTPC) is crucial for many applications, including neutrino oscillation analyses, and rare event searches such as coherent elastic neutrino-nucleus scattering (CEvNS) and low-energy nuclear recoil detection. Current R&D efforts are focused on testing gas electron multipliers (GEMs) in high-pressure environments, which is critical for optimizing the performance and reliability of HPgTPC systems. Results may be particularly applicable for DUNE Phase II, where a HPgTPC will be placed in the near detector complex to address one of the significant sources of uncertainty in neutrino oscillation analysis: nuclear effects in argon at the neutrino interaction vertex. This talk will present updates on the GEM simulation studies, as well as progress on ongoing test stands aimed at benchmarking the performance of the GEMs and electronics for placement in a high-pressure gaseous argon environment.
