Speaker
Description
We present a dedicated gas pixel micro-pattern gaseous detector (MPGD) developed for the direct observation of the Migdal effect. This detector integrates a gas microchannel plate (GMCP) and a high-resolution charge-sensitive pixel chip, using a He-DME gas mixture as the working medium. It features low noise, outstanding position resolution, and precise track and vertex imaging performance, which provide key advantages for identifying rare Migdal events in neutral particle-induced nuclear scattering. We also introduce the ongoing research progress on next-generation detector optimization and front-end electronics upgrading, which will further boost detection sensitivity, lower energy thresholds, and advance the application of this MPGD in light dark matter detection and other rare-event physics studies.
