[dsg-hallb_rich] [New Logentry] RICH Sector 1 gas system readout chassis replaced

[Tyler Lemon]

Hi Dr. Rossi,

I've submitted a PR for a new spare and it looks like Patrick (the new Hall B Group Leader) has already signed it.

Hi Dr. Rossi,





Yes, it would be best to order a new spare specifically for RICH.



It looks like the price will be $1,163.00. I will submit a PR today since it'll take some time for it to be delivered.





If something like this does happen again until the spare arrives, DSG does have other compatible chassis that could be swapped in if needed.

Very well! Thanks

Do we have to order now another spare?

RICH Sector 1 cooling air flow, cooling system buffer tank, and nitrogen purge flow reading dropped out (incorrectly read zero).

In the past a hard reboot of the system resolved the issue but the failure kept occurring after reboots.

The expansion gas system readout chassis that monitors those sensors was swapped out for a spare, resolving the issue.

RICH S1 hardware interlocks are now back to normal operating conditions.

Marco Mirazita has turned HV and LV back on for the detector.
