Update:
- HVPS cable wasn't grounded. It is now, but PSS Still trips.
- Issues performing sweep due to PSS configuration error
- Cathode grid possibly gone. Need to replace cathode
- Two dead pico-amp meters, flow meters are not working. Note: All of these items and computer for HVPS Software are on same fuse box.

-*Overview:
+*Update:
-** RF power to voltage relation- Complete
+**HVPS cable wasn't grounded. It is now, but PSS Still trips.
-** See RF waveform "clipping"- complete (Need different optical link)
+**Issues performing sweep due to PSS configuration error
-** DC bias fix- needs bench testing
+**Cathode grid possibly gone. Need to replace cathode
-** Quasi-bake of gun- complete
+**Two dead pico-amp meters, flow meters are not working. Note: All of these items and computer for HVPS Software are on same fuse box.
-** OSP- 8/6-8/7
-** HV processing- In progress
-** HV processing with solenoid on- sometime in the future
-** RF matching- sometime way in the future
-*Talking points:
+*Talking Points:
-** HV Processing over the weekend [https://logbooks/book/gtslog]
+** Cathode/Grid Issues, risks and risk mitigation
-** Krypton processing?
+** HV Processing (cathode hot/cold, Krypton)
-** Double click on the dial; not around it
+** Mini-flange leak valve?
-** Optical-fiber link (need check voltage output of current unit and order)
+** larger Ion pump?
-** Run without RF to have something for NAPAC (doesn't require DC Bias fix)
+** extra shielding on HV Cable or move supply again?
+** Change power source (fuse box) for racks?
