SVT InstructionsBefore sending beam to Faraday cup, verify (and page expert if otherwise):
The first time sending beam to the Faraday cup after the hall is closed, page the SVT expert.
Acceptable Beam Conditions:Before accepting beam, make sure all the conditions are met - beam profile and halo rates are what you expect (or very close to it). If unsure call to RC, PDL, or beamline expert!
Always read previous log entries, compare settings of BPMs and correctors with previous settings using scaler_hps GUI. Every Run:

At 6 am on Thursday, March 25, terminate beam delivery, turn OFF chicane magnets and ask MCC to sweep the hall and go to restricted access. It is important to have Hall-B in restricted access at 7am!
Run Plan:March 23-24, 2015 (day/swing/owl)Overview: Upstream BPMs successfully calibrated yesterday. Machine down much of the night with CHL trip and vac trip.Resuming program today. Program: 1) MCC re-tunes upstream beam;(2) When beams are acceptable, MCC restores beams to alcove;(3) When decent beams have been reestablished, calibrate downstream bpms (4) post calibration, require good spot on Chromax, low counts on halo counters, and then set-up chicane. 5) scan target vertically and horizontally, measure halo rates vs target; (5) Take data. Subsystem commissioning studies: more trigger commissioning studies, beam trip studies once orbit locks are on. MCC works on beam optics and matching, and tunes beam to tagger
Standards are on this page: ACCEPTABLE BEAM CONDITIONS.
Restore Beam to the Hall-B Dump
Energize Chicane
Be very careful when changing magnet currents when beams are on. Must enter new current ACCURATELY. Small steps (few amps) only.
Are we centered?
Subsystem Commissioning Studies. Begin Data Taking.
