Greg, the degrader foils in the 0L region are intact, thank you for the TLC. Marcy left a comment, but in Tony's harp assembly ATLIS... "checked degrader foils that were vented to do this work - all is good: https://logbooks.jlab.org/entry/4456860"

The external transformers in 1L09, 1L12, & 1L13 were detached and staged at the roll up doors in the North Linac Service building. Also, the diode stacks were disconnected and placed in front of the their respective zones for 1L09, 1L12, & 1L13.

Southeast Recombiner (INST#1) cable pull complete. Ready for termination. Will be looking to do either Southwest Spreader:(inst#2) in W2 or Northwest Recombiner:(inst#3) in NL01 next. Might be able to perform the next pull friday but will need to coordinate. If we can do it then I will announce it here.

Safely locked out NL01B01.
Disconnected channels 4, 11, 21, and 28 from NL01B01. The cables have been stored safely under the rack. These cables will need to be spliced to reach NL01B11.

returned pumps to ISB supplies, verified prior operating voltages and that cable labels on both ends matched. Thanks Ken. Voltage still needs to be fine tuned

ion pumps moved from local supplies to new commercial supplies in ISB. All are on and look good. Final voltage setpoints still need to be determined by CIS.

Leo installed gamma ion pump power supplies in the service building after removing the UHV ion pump power supplies.
Today
1) set gamma supplies to approximate voltage that the UHV supplies were operating at
2) powered off local supplies, moved cables to patch panels to ISB
3) energized ion pumps on new commercial supplies

I still need to do a bit of work characterizing current vs. voltage to set optimal conditions for the new supplies. This is just front panel operation, and I'll leave the atlis open until this final characterization is complete.

Turned off ion pump VIP0I04A (chopper 2) to see if turning any one pump off fixes blips. Also noticed that chopper temperatures dropping since Monday, and vacuum is improving correspondingly.

VIP0I04A off around 14:30 today

degrader ladder foils look fine after work to replace nearby harp.

Note - you can always vent at the 0L02B ion pump for this region. Our group just uses pinch valves to back up right angle valves, that would have been fine to open there rather than at the DP station.
