Description
The Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) will undergo extensive Phase-2 upgrades during the long shutdown 3 (LS3) scheduled to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). One of the most prominent aspects of the upgrade will be the introduction of a new detector sub-system, the MIP Timing Detector (MTD), situated between the outer tracker and the electromagnetic calorimeter. A new CMS timing detector will measure minimum ionizing particles (MIPs) with a time resolution of ~30-40 ps. The precision time information from this MIP timing detector (MTD) will significantly reduce the effect of pileup at the HL-LHC, bringing new capabilities to the CMS detector. The MTD will be composed of an endcap timing layer (ETL), instrumented with low-gain avalanche diodes (LGAD), as well as a barrel timing layer (BTL), based on LYSO:Ce crystals coupled to SiPMs. In this talk, we present an overview of the MTD design, describe the latest progress on prototyping and production as well as test beam results. In addition, we discuss the possible application of LGAD sensors at the EIC.
