HEP-Astro Seminar | Picosecond Timing: extending the physics potential of the High Luminosity LHC with the CMS MIP timing detector

The High Luminosity Large Hadron Collider (HL-LHC) is an upgrade to the Large Hadron Collider at CERN, which will extend the accelerator's potential for new discoveries in physics. This upgrade will increase the rate of collisions by a factor of five beyond the original design value and the total collisions created by a factor ten. To meet the challenging conditions of the HL-LHC, the Compact Muon Solenoid (CMS) detector is undergoing an extensive Phase 2 Upgrade program. In particular, a new precision timing detector with hermetic coverage up to a pseudo-rapidity of |η|=3 will measure minimum ionizing particles (MIPs) with a time resolution of 30-40 ps. This measurement of the time coordinate will reduce the effects of the high levels of pile-up expected at the HL-LHC and bring new capabilities to the CMS detector. In this seminar, I will discuss the impact on the HL-LHC physics program as well as the design and technology of this new detector.
