I started tonight by using backpropaGator to use Ben's data to match at 0L03 given MQJ0L02 and 0L02A's off design value. However, beam was still a stripe at viewers 0L03 through 5, and ok afterwards. at that point Yan arrived and helped us get a bit more on track by hand tweaking the quads. Afterwards I spent quite a bit of time steering out BLM trips. Collinearity is not very good, but I'm not too mad about it's later orbit. Figs 1 through 6 are a viewer walk (note the slight tail), fig 7 is transmission numbers (got >95 but still a bit on A3/A4), and figs 8, 9, and 10 are B, C, D respective orbits to A.

Noticed cavity 3 SOSing first. Tried OLT. Kept SOSing over 4 MV/m (ODVH = 5.5 MV/m). Noticed much more negative GLOD than usual for ~0.40 kW CRFP. CRFP also seemed pretty unstable.

While OLTing cavity 3, cavity 4 starting SOSing. OLT'd cavity 4 but it would SOS again over ~7.5 MV/m (ODVH 12.7 MV/m).

Left cavity 4 at 7 MV/m and cavity 3 at 4 MV/m. Pair is stable for now there.

2L08-8 RF repair and restore, broken cable/connector GMES. 2L08-3 developed Filament Volt High Fault getting back into filaments. 2L09-6 still has 0.0V CWWT voltage after IR cards swapped, needs SRF check IR voltage out of cryo-module. 2L14-6 has no CRFP but good CRRP, needs RFCM replaced, 2L16-6 TDETA unstable due to incorrect CRFP/CRRP readbacks and phase loop not locking, needs RFCM replaced. 2L19-6 has no CRFP/CRRP readbacks and needs RFCM replaced. 2L21-6 had KMAI faults due to filaments at 6.9 V and KMAV of 2kV, KCCU at .9 A.

Found the KMAI at over 3.5mA, KCCU at .9a with KFVM set at 6.9v with 2kV KMAV. Set filaments back down to 6.2v with 0.0 KMAV and tube is recovering to a KCCU of .79A with 1.668mA KMAV. Will need to leave run here over night to see if the tube KCCU get better that .79 A.
