Beam Test Measurements Using a New Front-End Readout Chip for the Future CMS Tracker — •Ali Harb — DESY

For the High Luminosity LHC (HL-LHC), a major upgrade is foreseen for the CMS experiment. In its Phase II, the accelerator will achieve luminosities up to 5×10³⁴cm⁻²s⁻¹ or more. To cope with the increased rates and occupancies, CMS replaces the current tracker with an entirely new system which is able to withstand the increased radiation corresponding to ∼ 3000fb⁻¹ integrated luminosity and resolve ∼ 200 collisions per bunch crossing while being able to provide information to the first level trigger and maintain the excellent tracking performance.

An extensive R&D programme has been launched in order to investigate novel technologies. It is foreseen that the future detector modules provide trigger information by means of an on-board p_T discrimination. To achieve this, a new front-end readout chip, the so-called CBC, is under development in 130 nm CMOS technology.

Results from the first test beam campaign with prototype modules utilizing the new front-end chip will be presented.
