Current run information

Fall 2016 GlueX production run

Run configuration:

  • Beam energy: 11.632 GeV
  • Solenoid on at 1350A.
  • Beam current: CW 1 nA-1.5 μA. 250 MHz frequency.
    • Goniometer diamond radiators: TBD. Specific meeting to discuss this to come. We presently have test diamonds:
      • J1a50 (50 μm, 4.1·10-4 R.L.),
      • JD70-118 (20 μm, 1.6·10-4 R.L.), middot;10-4 R.L.),
      • JD70-119 (20 μm, 1.6·10-4 R.L.), middot;10-4 R.L.),
    • and possibly some new diamonds
      • J70-100 (55 μm, 4.5·10-4 R.L.),
      • J70-105 (60 μm, 4.9·10-4 R.L.),
      • JD70-104 (23 μm, 1.6·10-4 R.L.), middot;10-4 R.L.),
      • JD70-108 (17 μm, 1.6·10-4 R.L.), middot;10-4 R.L.),
  • Tagger quadrupole on (-4.2 A).
  • Collimator hole: Both 5 mm diameter and 3.4 mm diameter. Default running: 5.0 mm
  • Target: LH2 target: cryogenic target

Schedule for the Spring 2016 run
