Figure 1 - Alarm handler window when there is a red alarm. If nothing is alarming, it would be grey.
Figure 2 - Hall A General Tools screen (beam is off), where you can find most of the information needed here.



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
  • Is the volume up on hacweb7? (both hardware and software)


Hall A Tools and related menu screens

  • Beam Energy (GeV)
    • Look at the lower left green "beamline" box
    • The beam energy can be found in the upper right of this box
  • Beam current (µA)
    • Look on the
  • Downstream raster (B) on? Yes/No (upstream raster is not in use)
    • picture of scope when raster is off, and when raster is on
  • Raster size (x:y mm, see log 3654466 )?
  • Fast feedback on? Yes/No
  • Beam Position Monitor X/Y (mm) A
  • Beam Position Monitor X/Y (mm) E (BPM B in Hall A Tools)
  • 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
  • Arc energy NMR locked? ( (Goto ARC or the "Field Management Screen", and verify if the box locked is ON/OFF))
  • VESDA System OK? (VESDA is the smoke/fire detection and alarm system. Check the Hall A VESDA Console on the wall behind the door
  • Current Target
  • Argon pressure (psi)
  • Ethane pressure (psi)
  • CO2 pressure (psi)
  • Visual Hall Inspection OK?
  • Septum current (A) and polarity?
  • Upstream/downstream corrector currents (A) ?
  • Check the scalers
