1. CLAS12 trigger

  • VTP status: use space driver maps FPGA space; i2c and serial peripheral interface (spa) exist on kernel, Bryan developed user drivers in final stage, will control on-board clock etc devices; will be finished this week, and will concentrate on registers communication (readout list etc) next week - all 3 of us
  • PCAL/ECAL algorithms: PCAL is completely implemented, preliminary checked by event display and by Vivado HLS, some parts have to be optimized (sorting and 2-dim cluster finder to be optimized in HLS); recent changes in algorithms includes double-peak handling and energy split for peaks shared by different clusters; one library is used now for both ECAL and PCAL, recognition between them is done by preprocessor flag USE_PCAL

2. Drift Chamber Readout: 18 crates on Subway are installed and cabled, fibers installation in progress and will be completed in few days, Linux loaded, starting DAQ testing
