This is a culmination of information about the Hall A Neutron Detector (or HAND for short).

Make sure the High Voltages are turned on
- This is done on the HV GUI (run from adev@adaql3)
- The important channels are listed in the Neutron Detector HV Map.
  
  Neutron Detector on the HV GUI
  (The HV in the map are not up to date, but the PMTs to HV GUI Channels are)
  - This includes all channels in crate bbps1:2001, all of slots 0, 1, 2, and 3 in crate bbps:2002, and the up to channel L4.3 in slot 4
- If a High Voltage Alarm sounds, turn the channel off and then back on
Run the RHRS CODA with the setting "RightHrs"
Analyzing the RHRS using do_all(run#) will analyze the neutron detector data
To view just the HAND data once replayed, use the command show_all(run#)
- It's the window where every group of histograms has labels that start with "ND"
In general,
- the ADCs should look like this:
- and the TDCs should look this:
- If they don't, make a HAlog entry about it
