seal-questionThe DAQ Is Broken... What Do I Do?

A step-by-step guide for decision making when it comes to working out how to fix the DAQ (in my experience!).

Step-by-step things to think about

1

Restart the DAQ

If the DAQ stops, ask the shifter (if they haven't done so already) to restart the DAQ from the VNC (they should already know how to do this, but if they don't just remind them).

2

The new run failed... what now?

If the next run also fails, the shifter should call/ping you on Slack. Now it's up to you primarily to fix it!

3

Check the message viewer

Look to see if there are any obvious errors in the message viewer:

  • If there is a PTB-based error, ping the PTB expert.

  • If there is a DQM-based error, ping the DQM expert.

If the CAEN looks to be the problem, then check out the 'Working with the CAENs' section of the notes.

4

If there are no obvious error messages...

In extreme circumstances, you may need to turn some components on and off again.
