gun bake update - end of day

Log Number: 4549032Logbook(s): Entry Makers: marcyBody: 

Moved control to the flange closest to the heaters (4.5" ion pump flange) so max temp is 250. All parts of the bake are now at temperature, mostly a bit below 250C since they are farther from the heaters.

**Energized overboard bake ion pump: Ion pump on cart reading in 10^-7 Torr range - tried turning on overboard ion pumps, which is at 120 C, and it came on at ~400 uA. Leave this on, close valve between turbo cart and overboard IP.

IMPORTANT NOTE. If there is a power failure over the weekend that effects the emergency power loop in the north linac contact me (office x7660 rings through to cell) or page Frank Humphry using staff search so that we can come in and confirm that vacuum is still happy.

2 Oct. 1L07 update. We finished processing all of the cavities one time. We will process them a second time on Monday and should be done by early Tuesday afternoon.

At the end of the shift. We secured the RF and turned off the amplifiers. We closed off the gas supply valve at the cavity gas supply* valve.

COMMENT ON Replace gun HV electrode

Gun bake going well, the high voltage chamber components settled at the ~250C soak w/ adjacent vacuum components following as needed. We had a good coordination meeting at the gun this morning to monitor the bake over the weekend, we'll be visiting later Friday, a few times on Sat and Sun. If the bake goes as planned we'll be activating NEG's by the end of the weekend and ramping toward RT on Monday.

MSSG:

We have completed all magnet work @1L26 warm region girder and all magnets and components carted and staged. Made LCW lines to keep all LCW up and functional in this region, to ensure Frank and companies turbos and related vacuum remain in line with LCW on.

Will begin work @1L27/NL on Tuesday.

COMMENT ON Plasma processing during the Fall 2026 SAM

3 days 23 hours ago
Log Number: 4548979Logbook(s): Body: 

Plan for vacuum system when we are done processing 1L07. I discussed the path forward next week with Frank H. Once we get things back on ion pumps we will close the valves on VIP1L07B and VIP1L08A. The beam line valve VBV1L07B will remain open. We will leave the plasma turbo cart on and pumping the vacuum manifold out to the closed valve on VIP1L07B. Frank will then be able to close the gate valve between the beam line and the getter pump on VIP1L07B and reactivate the getter pump while the beam line is being pumped by VIP1L08A ion pump.
