Before sending beam to Faraday cup, verify (and page SVT expert if otherwise):
The first time sending beam to the Faraday cup after the hall is closed, page the SVT expert.
Acceptable Beam Conditions:
To establish good beam conditions first send beam to the tagger dump (ask MCC to turn ON the tagger).
While MCC degausses the tagger magnet, turn the chicane ON
Before sending beam to the Faraday cup
Beam to the Faraday cup
Before accepting beam, make sure all the previous conditions are met. Always read previous log entries, compare settings of BPMs and correctors with previous settings using scaler_hps GUI.
Run Plan: April 23-30, 2015 (day/swing/owl)
During week days, Mon-Thursday, there will be no Day shifts due to work in the hall.
Short Term Schedule: Study Trigger and SVT running conditions.
We will be running with 1.05GeV beam. This beam needs to be carefully restored, first to the tagger dump, then the alcove and Faraday cup screen. See detailed instructions in the left pannel.
Then, proceed with program
Notes: If you change beam current current, turn orbit locks off first, there is a current - position dependence on the stripline BPMs 2H00 and 2H02. Do NOT change magnet currents when beam is on.
DO NOT RUN MORE THAN 30 MINUTES ABOVE 50 nA WITHOUT THE BEAM BLOCKER
