Run Plan:March 20-21, 2015 (day/swing/owl)Overview: Machine will concentrate on getting beam to Hall A, followed by attempt to send beam to Hall D. No beam to Hall B before mid swing shift. So day shift is cancelled, but swing and owl shifts are on. Plan to sweep around 3PM, Hall in restricted access until then. Invariant program: 1) restore beams to tagger; (2)take beams to Hall B dump and install SVT Collimator; (3)starting Mar 21 day shift, make beams available to machine for BPM calibration; (5)set up chicane and test beam location on target. Always Setup Beam to the Hall-B Tagger Dump after long down
Upstream halo counters must count <10Hz, downstream counters ~Hz
Setup Beam to the Hall-B Faraday cup Dump and Setup HPS.
Move beam with upstream correctors only This will guarantee small angles through HPS and safety of SVT
Beam should be centered using correctors on 2C21, 2C23, and 2C24 girder
Give beams to machine for BPM calibration asap in day shift. FIRST: must complete above to ensure beams are safely centered in SVT. If have extra time before day shift, proceed to chicane set up below. Energize chicane.
Be very careful when changing magnet currents when beams are on. Must enter new current ACCURATELY. Small steps only.
