Run Plan: Dec. 7 - Dec. 9

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.

Establish CW 1 pass beam to the Hall-B dump, including checkout of all new beamline components, BPMs, quads, correctors, and harps.
Work with MCC crew to establish small size stable beam at the alcove harp - beam parameters sig X ~ 150 micron, sig Y ~50 micron, with low noise in the downstream halo counters and ecal.
Perform harp scans using 2H02 harp. Optimize halo counter voltages as needed.
Once established, commission the chicane magnet, including a study of noise rates (halo counters + ecal) vs B field. (We may need to run slightly lower than nominal B for our given beam energy to afford adequate clearance to the 3 inch beam pipe connected to the new target assembly.The beam pipe must accommodate both straight through and Frascati bent beams.)
Commission the HPS target, including measuring noise rates in the Ecal and halo counters vs beam current.
If time allows, begin commissioning the Ecal and trigger with beam on target.
