Summary

 

Overview

His research interests are dominated by instrumentation for particle physics experiments at the CERN Large Hadron Collider, particularly now focused on extending the CMS operational lifetime into the high luminosity era from 2026. Radiation damage precludes survival of the silicon tracking sensors, and a replacement detector must have greater granularity and higher speed readout, as well as increased radiation tolerance. It must also provide data to be used by the CMS trigger to select rare events efficiently. The Imperial group has contributed several unique ideas to make this possible. The first is to deploy double-layer silicon modules (“pT-modules”) to identify high transverse momentum tracks, to design front end electronics, the CBC ASIC, to provide this information, and an off-detector system to process it.  In 2016, a team demonstrated the viability of FPGAs for sufficiently fast, efficient track reconstruction for the HL-LHC based on these ideas.
