<pre class="moz-quote-pre" wrap="">There are several ways to access the LabVIEW GUI if some of the expert functionality needs to be used.
The gas shed cRIO itself as you noted, but also the Windows computer in that room, plus the one in the counting house. Hall B Engineering has access, if Bob wants others' to have access that's fine as well.
As for any MFC spares, I can double-check, but I think all the smaller ones used for the MVT were handed over to Hall B once the system was installed.

2:30 am. MVT Ar fraction alarm. After resetting few times MVT gas mixing system, argon fraction returned to normal.
Waited for gas to flow through the BMT, powered up HV.
One more alarm at 6:24. Reinitialized MFC in the gas shed.
This alarm requires on-call experts to come to Lab as only DSG are allowed remote access to the gas LabView GUI. This causes delays and loss of beam time, especially at night.
This is the 3rd incident recently. Brian, Marc, can this MFC be replaced? Do you have spares?
