Run Plan

Production running cycling through targets:

  • JD80-212 80um diamond, 200 nA beam current
    • 800M events for 0/90 deg and PARA setting
    • 800M events for 0/90 deg and PERP setting
    • 800M events for 45/135 deg and PARA setting
    • 800M events for 45/135 deg and PERP setting
  • 400M events with 4.5×10-4 Al 40um radiator (on goniometer!), 300 nA beam current
    • Set new reference for amorphous radiator in CBREM GUI.
  • Runs no longer than 2 hours.

Special instructions

  • pi0 running
    • 300 nA beam current, 4.5 E-4 Al (amo, on the goniometer)
    • TAGH_HV_ProductionSpring2023_300nA.snap
  • Compton running
    • 100 nA beam current, 4.5 E-4 Al (amo, on the goniometer)
    • TAGH_HV_ProductionSpring2023_ALL_ON.snap

Medium Term (1 week)

  • Diamond Alignment
    • During normal business hours when beam is good. Friday??
  • Friday April 18
    • Presentation from Kondo in RC meeting
  • Next maintenance day (Wednesday April 23 possibly)
    • Restricted access for parasitic experiments
    • Crane use
    • SAF113 training at 9:30 am

Run conditions

  • Radiator: 4.5 E-4 Al (amo, on the goniometer)
  • Collimator: 5.0 mm
  • TPOL converter: Be 75 um
  • Runs are no more than 2 hours - see whiteboard for the production cycle
  • Target: Liquid Hydrogen
  • DAQ configuration - see whiteboard

Current Experiment
