| Abstract | A new CMS Tracker is under development for operation at the High Luminosity LHC from 2025. It includes an outer tracker based on PT-modules which will construct tracker stubs, built by correlating clusters in two closely spaced sensor layers for the rejection of low transverse momentum track hits, and transmit them off-detector at 40MHz. If tracker data is to contribute to maintaining the Level-1 trigger rate under increased luminosity, a crucial component of the upgrade will be the ability to identify tracks with transverse momentum above 3GeV/c by building tracks out of stubs. A concept for an FPGA-based track finder using a fully time-multiplexed spatially pipelined architecture is presented, where track candidates are identified using a projective binning algorithm. Results from a hardware demonstrator system, where a slice of the track trigger will be constructed to help gauge the performance and requirements for a full system, will be included. |
