Removed guards from target and reset Q2 power supply
Lead flows are unstable (instant highs and lows from 50 to 600 in the case of the right dipole). I reset it and it was fine for 1 min then it was bad again so I cycled power and it seems be better. But the display on the meter is dyeing so the meter probably is too.
The lead flow meters on the left Q1 are intermittent about 50%/ 50% on and off. This is causing a cryo fault and will not let the power supply start. The manual flow meters are rock stable.
The left are Q1 would not fill with both valves full open so I cycled power on the meter 4 times and it went to random numbers each time. I changed the meter and it went to 95%. I cycled power on it and it went back to 95% and then was controllable
I had a stuck LL on the right dipole and it was corrected with just a power cycle on the meter, however while I was in the hole I cycled power on all of the meters and found that the right Q1 and Q2 were random after a cycle and changed them too. Yes Jack I know but I have a witness!
We have a real instability on the right Q3 LL meter but that one is a cryo magnetics and I didn’t bring one with me. I may try that tomorrow.
In the end both Q2s are tripping with what appear to be stable cryogenics an fairly low current (500 amps). Left Q1 in not operational due to the flow meters (cryo fault). I will try to work on them tomorrow.
