Important SAFETY instructions
No access to the alcove if the chicane magnet beacon is ON.
Chicane magnets must be OFF if the hall is in Controlled access and access to the alcove is needed or when the hall is in Restricted access. If Chicane magnets are OFF, they can be energized only when the hall is in Power or Beam Permit, .
TURN OFF the chicane magnet if beam is not available due to a thunderstorm. Loss off power would seriously damage detectors.
Important general instructions
Fill out BTA hourly. Click "Load from EPICS" to fill the left side, then make sure numbers are correct. If needed edit the entry.
NO ABUs or BANU if beam tune is in progress, make it all BNA with ER 100%. At the end of the shift save BTA to the logbook!
Please close any GUI that is not being used, e.g. close harp scanner after harp scan is done, close chicane, after chicane is ON, etc.
For orbit lock positions on 2H00(X=1.0,Y=1.5) and on 2H02(X=-1.7,Y=0.3). Use the 2.82 mm SVT collimator
Run Plan August 19-20, 2019
SVT Bias Currents:
Shifters must pay attention to the L0 bias currents. This is on both the SVT motor GUI and the main bias GUI. The bias currents will slowly creep up over the course of a run. When the bias current is between 15-20 uA for either L0 sensor, do the following:
Do not let the bias current exceed 20 uA. It takes about 4-5 hours for the bias currents to creep up to those values. Call SVT expert if unsure.
Harp Scan Procedure:
Establishing Physics Quality Beam for HPS:
Note: in order to have reliable readings on two important for HPS BPMs, 2H00 and 2H02, beam current should be >30 nA.
