Run Plan: Dec. 8 - Dec. 10Beamline 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.
Record scaler rates, BPMs, 2H02 harp, and beam location on dump screen. Choose nominal position close to rate minimum, at old nominal, if possible.
location on dump screen. Tweak Frascati current if necessary, and record. Record scaler rates.
