The Charge Asymmetry Feedback system is controlled by the Hall A Parity DAQ.
When Hall A is in production mode, the Hall A shift crew will manage the Parity DAQ and control feedback for both Hall A and Hall C beams.
If the Hall A Counting House is not staffed, then Hall C must negotiate with the Parity group to ensure that the Parity DAQ is still running.
- This must be running for all 3He production data! (And should be running in general.)
- The state of this system is monitored in the Hall C alarm handler, and can be overseen by the Hall C Shift crew using the stripchart on the left large wall display (see below).
Instructions
- Parity DAQ Running - with Hall C Feedback passively running (Aug 02, 2020 HClog entry)
- Bring up this vnc session using
go_parity_feedbackunder the cdaq account.
- Hall C running parity DAQ for charge feedback (Feb 12, 2020 HCLog entry) -- OLD, just for reference.
Useful Commands
