Run Plan for February 26 - 29, 2016:Start close-up of the Hall at 3pm on Friday, March 4When hall reaches "Beam Permit", turn on the chicaneEstablish beam to the tagger dump
Bring beam to FC:
Miscellaneous Notes:

General Instructions:Locking up the hall on Fridays
Acceptable Beam Conditions:To establish good beam conditions:
Recovering from beam trips when running SVT at 0.5 mm:
Every Shift:
Every Run:
Setting up Chicane for E=2.3 GeV:Note: This requires Beam Permit and NO beam to HPS / Faraday Cup.
