      • Triggers (PARA 354M trigs, PERP 375 M trigs)
      • High luminosity tests (30 minutes), trigger studies (4 hours)
      • Run Statistics
    • Hall D access Wednesday 20 April.
      • RadCon has been contacted.
      • Access possible in the morning
      • Beam studies in the afternoon (upstream slow locks)
      • Walkthrough (Hall and Tagger)
      • Collimator work
      • TRD work
      • Magnet work
      • FCAL bases exchange
    • Microscope gain balancing
    • Report on Trigger studies
