General Information

Run Configuration

  • Beam energy: 11.632 GeV
  • Solenoid on at 1350A.
  • Beam current: CW 1 nA-2μA, 250 MHz frequency. See RSAD for the RadCon limitations.
    • Regular running: 150 nA on 4.1·10-4 radiator
    • High intensity tests: 3 shifts at 1 µA on 4.1·10-4 radiator
  • Diamond radiators:
    • J1a50       (50 μm - 4.1·10-4 R.L., 4×4 mm²) - old crystal - excellent rocking curve
    • JD70-100 (58 μm - 4.8·10-4 R.L., 7×7 mm²) - new crystal - excellent rocking curve
    • JD70-105 (47 μm - 3.9·10-4 R.L., 7×7 mm²) - new crystal - good rocking curve
    • JD70-104 (17 μm - 1.4·10-4 R.L., 7×7 mm²) - new crystal - wider rocking curve - marginally usable
  • Tagger quadrupole on (-4.2 A).
  • Collimator hole: 5 mm diameter with ≈50 µm diamond radiators, may use 3.4 mm diameter with ≈20 µm diamonds
  • Target: LH2 target

Schedule Details

  1. Oct. 1st-Oct. 7th: Electron beam restoration
  2. Oct. 8th-Nov. 22nd: Hall D Fall run, part 1.
  3. Nov. 23rd-Nov. 27th: Thanksgiving break.
  4. Nov. 28th-Dec. 18th: Hall D Fall run, part 2 (includes 2 day of beam restoration).
  5. Dec. 19th-Dec. 21st: TBD
  6. Every Tuesdays: 12h of beam study. Every Thursdays, if necessary: 8h of RF recovery.
