Description
The CGEM-IT (Cylindrical Gaseous Electron Multiplier – Inner Tracker) is the new inner tracker of the BESIII experiment, based in Beijing. It consists of three layers of cylindrical triple-GEM. It deploys a dedicated readout chain based on TIGER (Torino Integrated GEM Electronics for Readout) ASIC and GEMROC (GEM-Read Out Card) readout cards to collect signals from the approximately 10000 strips of the entire detector. Before the installation, a standalone commissioning with a dedicated cosmic ray stand has been performed to verify the resolution and the efficiency, together with the detector operation stability. The CGEM-IT was successfully installed in October 2024 and has been commissioned with cosmic rays and beams since March 2025, and will continue with a dedicated data taking at psi(2s) peak center of mass energy until the end of 2025.
In this presentation, the CGEM-IT detector will be discussed with details on its operation inside BESIII and preliminary performance with cosmic rays and beams.
