      Scintillator cut with a laser processing machine 40m
      Sprecher: Sho Nagao (Tohoku University)
    • 09:40 10:10
      Update on status of Kaos spectrometer 30m
      Sprecher: Philipp Eckert (KPH Mainz)

      short summary (no slides):
      - Kaos works after switching on -  faster than expected, only minor issues
        - Plots for scintillator walls looking good (cosmic runs) 
          - only fine-tuning will be required (threshold, PM voltages), will not be done with cosmics
          - only a single paddle without signal ( PMs working properly, issue discovered in CFD/ADC branch (cabling?) - should be a rather easy fix
        - Cerenkov detectors
          - some issues here: too low HV in cosmic test run? (voltages were below values in logs from previous runs, fixed for next test run (in the next days))
        - reconstructed tracks:
          - already nice correlation bands in most paddles
          - HV issues in cerenkovs also visible here
        - To Do's: 
           - stability issues (camac error, unphysical trigger rates, loose contact?)
           - check Cherenkov detectors (HV?)
           - Scintillators (check CFD issue in "defective" paddle)
