Run Plan: Dec. 8 - Dec. 10 Beamline commissioning studies using the Hall B dump, followed by studies of the ECal and Trigger. The goal is to get usable CW beam to the Hall-B dump, set up the chicane, and begin to study beam backgrounds and trigger rates. Re-establish CW 1 pass beam to the Hall-B dump, setting beam to specified settings at the dump screen and the 2H02 harp. Chicane off. 5 nA. Study the dependence of halo counter rates on beam position. Vary x and y of beam by +/- 7.5 mm, with beams parallel to specified settings above. Record scaler rates, BPMs, 2H02 harp, and beam location on dump screen. Choose nominal position close to rate minimum, at old nominal, if possible. With beam at nominal, set up chicane to specified currents for the -7% field point. Instructions provided in Counting House. Verify harp scan and record location on dump screen. Tweak Frascati current if necessary, and record. Record scaler rates. Ditto for -9% beam position. If little change in scaler rates, use -7% setting as chicane standard. If large improvement in scaler rates in going to -9%, try -11%. Select standard chicane settings. Commission the HPS target, including measuring noise rates in the Ecal and halo counters vs beam current. Call Stepan before first use of target. With 1.5 um Pt target, measure scalers and Ecal occ vs beam current.Record Ecal Scalers and scalaer display for each beam current. If time allows, begin commissioning the Ecal and trigger with beam on target and data taking. Expect beam off Tuesday day shift for machine studies. Beam recovery starts on Swing.
