Description
The High-Luminosity LHC (HL-LHC) will require silicon-based tracking at 40 MHz in the Level-1 trigger system to maintain manageable trigger rates due to high pileup conditions in the CMS detector. An important component of this system is the Level-1 Track Finder (L1TF), which reconstructs charged-particle tracks from stubs (pT > 2 GeV correlated pairs of hits) generated in the outer tracker.
This poster presents recent progress in the development of the L1TF data processing chain. With the use of a Cosmic-RACK (C-RACK), we have successfully established a workflow from detector data acquisition (DAQ) through the Data and Timing Hub (DTH) to usable physics objects. Key achievements include implementation of the cluster unpacker in CMS Software (CMSSW), which converts raw detector data into reconstructed clusters, validated through tests with simulated data. Current work focuses on integrating the data processing chain with the Data Quality Monitoring (DQM) system and addressing remaining challenges in stub processing. We highlight the current status, recent milestones, and open tasks in preparing the L1TF system for HL-LHC operations.
