中国物理学会高能物理分会第十一届全国会员代表大会暨学术年会

The HL-LHC will run with 5 times higher instantaneous luminosity than the LHC. Severe pileup effect significantly degrades the physics sensitivities. MIP timing detector (MTD) is designed to provide precise measurement of the timing of MIPs to the level of 30 ps, and can bring remarkable identification performance of pileup vertices, which keeps the HL-LHC physics programs attractive. This talk will introduce the design of MTD, particularly for the barrel, and will report the current status of the Chinese participation in this upgrade program.
