ToF non-linearity test. Fast raster beam characterization Muon chamber test (parasitic) TRD test (parasitic) 2017/12/04 - 2018/03/23, (with Dec. 18th-Jan. 8th Xmas break). 12 weeks; 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 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 Nov. 27th-Dec. 3rd: Electron beam restoration Dec. 4th-Dec. 18th: Hall D Fall run. Dec. 18th-Jan. 8th: Xmas break. (Solenoid will be ramped down, but kept cool.) Jan. 9th-Jan. 11th: Electron beam restoration Jan 12th-Mar. 23rd: Hall D Spring run. Every Tuesdays: 12h of beam study. Every Thursdays, if necessary: 8h of RF recovery. List of Run Coordinators and Physics Division Liaison PDL: Benedikt Zihlmann RCs: Nov. 27th-Dec. 3rd, 7 days: A.
