Hall C – this week Time Period Plans 10/24-10/27 Target cool down Restricted access Lockup by swing shift Radcon checklist Complete ion chamber calibration Detector checkout (5 pass) 10/27 Energy change Optics checkout (2 pass) 10/30 Start production data taking Ebeam=2.528 GeV (5 pass) Need combined optics (Moller quads ON)
Hall C – Beam Requirements Type Requirement Positions (Δx, Δy) < 0.2mm Energy < 5 x 10-4 ΔE/E < 10-4 Beam size 100 x 100 μm Raster 2 x 2 mm FW Polarization As high as possible Beam currents Up to 80 μA Beam Polarization will be measured using Hall C Moller
Hall C – special tasks BCM calibration Moller commissioning during Ebeam=2.528 GeV (after 10/30) First energy measurement and BCM calibrations during Ebeam=4 GeV (800 MeV) running (11/6?)
