Experiment: GlueX E12-06-102 Production
Planned tests:
- High-intensity GlueX test (invasive, 3 shifts)
- ComCAL(PrimeX) prototype test (parasitic)
2017/01/29 - 2017/03/22, 51 days; see Accelerator Schedule

Hall D run logbook (HDLOG)

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

Jan. 26th-Jan. 29th: Electron beam restoration
Jan. 30th-Mar. 22nd: Hall D Spring run.
Every Tuesdays: 12h of beam study. Every Thursdays, if necessary: 8h of RF recovery.
