Overview: Machine will stop at noon for LCW heat exchanger replacement. No beam to Hall B before noon. Machine restarts ~5PM. So day shift is cancelled, but swing and owl shifts are on. Beams to Hall B scheduled for swing, so shift should go to controlled access in preparation and sweep hall when beams are imminent. Beams are expected mid-late swing. Program same as yesterday: 1) restore beams to tagger; (2)starting Mar 20 day, make upstream beams available to machine for BPM calibration;(3)take beams to Hall B dump; (4)make downstream beams available to machine for BPM calibration. | Overview: Machine will stop at noon for LCW heat exchanger replacement.

Run Plan:March 19-20, 2015 (day/swing/owl)Overview: Machine will stop at noon for LCW heat exchanger replacement. No beam to Hall B before noon. Machine restarts ~5PM. So day shift is cancelled, but swing and owl shifts are on. Beams to Hall B scheduled for swing, so shift should go to controlled access in preparation and sweep hall when beams are imminent. Beams are expected mid-late swing. Program same as yesterday: 1) restore beams to tagger; (2)starting Mar 20 day, make upstream beams available to machine for BPM calibration;(3)take beams to Hall B dump; (4)make downstream beams available to machine for BPM calibration. Always Setup Beam to the Hall-B Tagger Dump after long down
Upstream halo counters must count <10Hz, downstream counters ~Hz
Give Beams to Machine beginning of day shift for BPM calibration of upstream beamline. If have beams to tagger well before day shift, proceed with set up to alcove until 8AM. 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 of downstream beamline. Energize chicane.
