中国物理学会高能物理分会第十三届全国粒子物理学术会议（2021）

This talk will present current status of the CMS Phase-2 endcap calorimeter upgrade (HGCAL) project, with a major focus on the R&D activities of the CMS-HGCAL team in China working on the silicon modules. A dedicated silicon detector lab on IHEP campus in Beijing has successfully been developed and will serve as one of six MACs around the world. The lab is now being commissioned for the silicon module assembly with essential quality control procedures. Several test stands have been developed to evaluate the module performance. Besides a general overview of the HGCAL project, future plans and prospects of the silicon modules will also be briefly covered.
