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

Handy beam current monitor monitor with A1 HVB current

Before deployment, the AI was initialized, when the CDC's HV and the beam current were at their nominal values. This was done by running ./initai.sh This wrote the D1 max temp in K and the mean AI HVB current into the file defaults.txt which is read in by runai.sh.

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