Forward power changes with gradient and tuner movement when both loops are open. Shouldn't it stay roughly constant once the GLOD is set to put ~0.4 kW into the cavity?

Tuning didn't do much here.

At least when setting GLOD for open-loop tuning, the CRFP readback stays at zero for quite a while after gradient appears in the cavity. Tuning seems to have done some good for this one, though I did trade a little klystron reflected power to bring the GASK way down. Don't mind the very long excursion I took with the tuner in the middle there, I was probing some weird behavior in the detune angle.

This cavity detunes wildly every time it trips. I tried to find the best spot to zero the detune angle but it may need to be revisited. I'll run trim up/trim down when I'm finished with this zone as well.

This cavity is "not ready" by RF in SRM. It was bypassed as recently as last night but the most recent entry in cavity history was 29 Jan. I just went ahead and re-bypassed it so the RF on button doesn't keep trying to wake it up.

Steered down interception with up to a total of 40 uA CW from all four lasers. The lowest I could get A3 at this current was 2.8 uA.

ILM0L02 was tripping with ~8 uA of CW only when sending the B laser. Seems to improve considerably when the 0L02.XPOS is made more negative. With the pictured orbit, the BLM is quiet with ~40 uA CW from all four lasers.
