Run Plan:March 18-19 (swing/owl/day)Overview: Close up Hall B during swing, sweep, and go to beam permit. Beams are expected beginning of owl. Program then will be to (1) restore beams to tagger; (2)starting Mar 19 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. Setup Beam to the Hall-B Faraday cup Dump and Setup HPS.
Beam should be centered using correctors on 2C21, 2C23, and 2C24 girder. Correctors at 2H02 have been disabled.
Give beams to machine for BPM calibration of downstream beamline. Energize chicane.
