These improvements are expected to go into the next round of reconstructed data:

  • improved CDC dE/dx calculation
    • use of ADC amplitude instead of integral - dE/dx vs theta
    • updated truncation value
  • improved TOF calibrations
    • use of ADC amplitude instead of integral
  • new SC attenuation length corrections
  • BCAL charged track clusterizer
  • FCAL updates
    • Updated gains (fix problems with inner rings)
    • Updated timing (fix high-rate running problem)
    • Update geometry?
  • updated charged/neutral error matrices?

Outstanding questions:

  1. What is the bump in BCAL & FCAL monitoring delta T distributions at +4 ns?

  2. What is the bump in SC monitoring delta T distributions at ~ -8 ns?
  3. What is the inefficiency in the TOF matching efficiency near the beam hole due to?
