PrimEx instructions

Log on to the counting house bluejeans and talk to the shift leader. The shift schedule is linked here .

Start up a VNC session, following these instructions

To run the AI, gathering epics for the previous minute:

• Logon to gluon47 as hdops
• cd /group/halld/Users/njarvis/aiec
• ./runai.sh

If the beam is fluctuating more usual, you might want to run it for the previous 2 minutes instead:

• ./runai.sh 2

Set the HV back to 2125 V when you finish

Before deployment, the AI should be initialized, when the CDC's HV and the beam current are at their nominal values. This is done by running ./initai.sh This writes the D1 max temp in K and the mean AI HVB current into the file defaults.txt which is read in by runai.sh. I don't think this is crucial as sensible defaults are in the file at the moment. 299K and 8.1A.

Both initai and runai append a summary into log.txt.
