11:00 → 12:00 IPM Electronics for the CMS Phase-2 Upgrade of the RPC Link System: The System Review and Validation (Part 2)

The phase-2 upgrade of the CMS RPC System for the low-eta region will enhance the electronics performance, and muon hit time resolution to cope with the High Luminosity Large Hadron Collider (HL-LHC) conditions. In the Compact Muon Solenoid (CMS) experiment, Resistive Plate Chambers (RPC) have between 36 and 96 strips read out by frontend electronics boards (FEB). The FEB outputs are connected to the IPM electronics known as the Link System, where 96-channel time-to-digital converters (TDC) implemented in a Kintex-7 Field Programmable Gate Array (FPGA) measure the arrival time of the muon hit at a fine-time resolution of 1.56 ns that is near to the RPC intrinsic time resolution. Additionally, the Link System will be installed in a radiation environment and must tolerate radiation effects. This talk will review the new Link System and explain how this system fulfilled the CMS Phase-2 upgrade requirements.

Speaker: Dr Behzad Boghrati (IPM & Damghan University)
