Bluejeans & shift schedule

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

Running the AI

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 unless the next shift taker will continue to use the AI.

Handy beam current monitor monitor with A1 HVB current

VNC session (optional)

If you need to start up a VNC session:

ssh -t -L59xx:localhost:59xx yourid@hallgw.jlab.org ssh -t -L59xx:localhost:5901 hdops@gluon48

xx is a number of your choice. The first pw is your own pw for halldgw. The next is the super secret one.

Then use Finder Go, Connect to server

The remote worker VNC instructions are here but don't use gluon03, that is for the remote worker.

Initialization

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. Next time Naomi should also put the gain correction factor for the run period into ccdb during initialization (as well as the default TTOD params).

Logging

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