- ComCAL(PrimeX) prototype test (parasitic)
- 2017/01/29 - 2017/03/22, 51 days; see Accelerator Schedule
- Information for shift takers
- Shift schedule
- Hall D run logbook (HDLOG)
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
