,g for Kr processing

1 day 23 hours ago
Log Number: 4549860Logbook(s): Entry Makers: mamunBody: 

We ramped up to 210 kV for HV vacuum conditioning and end up seeing field emission that was not going away at 210 kV. We then step by step lowered the HV and observed the field emission level correspondoingly lowered until it reached backgound noise level of 4-8 counts at 110 kV.
Next we will set Kr for processing the gun.

At the beginning of today's HV vacuum conditioning, the onset of vacuum desorption happened at ~162 kV. Over the HV vacuum conditioning, the gun tripped 3 times at 172, 183, and 185 kV respectively.

The new switch and fiber patch cables have been installed, and the switch is connected on the network. We will look at what needs to be done to move over the connections from the old switch to this new one, and I'll submit a new task at that point.

COMMENT ON E3 Convectron Controls Upgrade (2026 SAM)

2 days 4 hours ago
Log Number: 4549809Logbook(s): Body: 

With the success of the fix of the Valve interlock cable between E3 and E5 I have contacted Radcon to install new Radcon screw in rack E301B10 for the new panel holding the new convectron controllers.

Will continue to monitor and perform another HCO at the end of the week along with the Valve interlock controls at E5: https://tasklists.jlab.org/atlis/tasks/121068

If everything checks our I will close out Atlis/PTW.
