PREX Main<< Information for Shift Takers << Shift Leader << Shift Checklist
Alarm Handler
- Is alarm handler running on hacweb7?
- On hacweb 7, you should see a window in the upper right corner of the screen
- Look first in the "Alarm Handler" desktop to see if it is there
- Check all the windows if not
- If not open, see Alarm Handler
- On hacweb 7, you should see a window in the upper right corner of the screen
- Is the volume up on hacweb7? (both hardware and software)
Beamline
- Beam Energy (GeV) (see Figure )
- Beam Current (µA)
- Beam Position Monitor (BPM) X/Y (mm) A
- Beam Position Monitor (BPM) X/Y (mm) E (Called BPM B in Hall A Tools)
- Downstream raster (B) on? Yes/No (upstream raster is not in use)
- need a picture of scope when raster is off, and when raster is on, something like halog 3654466
- BCM temperature (K) (PV, PS, Thermocouple)
- If these differ by +/-.5 from (110.0,110.0,115.0) (Fahrenheit) contact RC and halog
- These temperature readbacks are located in the middle DAQ room, in rack CH0B06 (far left) at the very top
- It is important that these temperatures stay stable within 0.5 Fahrenheit or else the BCM current readout will become uncalibrated
- Raster size (x:y mm, see log 3654466 )?
- Fast feedback on? Yes/No
- Arc energy NMR locked? ( (Goto ARC or the "Field Management Screen", and verify if the box locked is ON/OFF))
Gasses
- Argon pressure (psi) (see Figure )
- Ethane pressure (psi)
- CO2 pressure (psi)
- VESDA System OK? (VESDA is the smoke/fire detection and alarm system. Check the Hall A VESDA Console on the wall behind the door
Hall/Counting House
- Visual Hall Inspection OK? (picture)
- Current Target (snapshot)
- Septum current (A) and polarity?
- Upstream/downstream corrector currents (A) ?
