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

Running the Neutron Detector

1. Make sure the High Voltages are turned on
   • This is done on the HV GUI (run from adev@adaql3)
   • The important channels are listed [http:/http://hallaweb.jlab.org/experiment/E05-102/Shift_Worker_HV_Map.pdf in the Neutron Detector HV Map].

     • 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
2. Run the RHRS CODA with the setting "RhrsND"
3. Analyzing the RHRS (using replay_R(run#) will analyze the neutron detector data
4. To view just the HAND data once replayed, use the command online("detectorND",run#)
5. In general,
   • the ADCs should look like the first row of this image:File:Http://www.jlab.org/~adaq/halog/html/0904 archive/090425180242.1.png
   • and the TDCs should look this:
   • If they don't, make a HAlog entry about it
