Follow-up Re: SLinac/FEL Flow Decrease
SC1R Flow Decrease is complete. We will remain at 185g/s overnight and plan to lower flow again in the morning with the goal of shutting down SBR C2 by the end of the day tomorrow (7/15) if we are able. SLinac Heater Margin is sitting around 30W/module.

HD Collimator Cave re-locked and posted
1L21-5,6,7,8 CWVF faults and all Low Gradient
2.5w AMP replaced in cavity 7 but had tuning and CWVF faults running above 3.3 Mv/m and detuned easily. Cavity 5 tuner/CRFP unstable issue was retuned but started to drop HV on zone when gradient raised above the 3.9 Mv/m. Monitoring KCCU after each HV attempt required a waiting period to let tube recover until it didn't and resistor blew. 1L21-5 re-bypassed and steppped off +100k steps.
