COMMENT ON RF work for 2026 HCO

21 hours 11 minutes ago
Log Number: 4474886Logbook(s): Body: 

More troubleshooting at 2L03 required. Removed Klystron jumpers and still had DC overcurrent trips. Some component in the CPS could be causing the overcurrent. Checked DC overcurrent circuit and it's working properly. Checked diode stack, but no clear sign of malfunction there.

Follow-up Re: Gun HV cable is removed for inspection, carbon track is observed on the insulator and the cable receptacle

22 hours 50 minutes ago
Log Number: 4474868Logbook(s): Body: 

Helium leak check gun ceramic insulator once silicone grease removed. No leak detectable using the RGA on the prep chamber.

In the process of removing the carbon trace using scotch brite pads - slow but steady progress. Once we are satisfied that as much of the carbon trace as possible is removed from the ceramic, we'll leak check again and resume tomorrow for installing a new high voltage cable.

COMMENT ON RF work for 2026 HCO

22 hours 57 minutes ago
Log Number: 4474867Logbook(s): Body: 

Replaced 2.5W amp, RFCM and drive is even lower that previous amp removed by 200w CRFP. After several external cable checks, might have to remove klystron drive heliax to check it for losses. Got 1L21 back into HV after several attempts. HV relay could be dirty and not making full contact or we have a loose wire on terminal blocks TB2 that will need checked if we loose HV permissives again. Recovered 1L21-5 but low drive on cavity 7 needs to be checked out. Looks like another 2.5W amp. Chris and Trey.
