TVo, Stefan We worked on getting the IFO locking again: - As we went through the initial alignment we noticed a few things: - ALS arm initial alignment: The camera feed-back gains are extremely low - we were able to increase the gain by x100 to make it converge faster. Also the ITMY green camera is now centered, and H1:ALS-X_CAM_ITM_PIT_OFS and H1:ALS-X_CAM_ITM_YAW_OFS are updated to reflect the same alignment as before. - Even though not needed, we also tried the automatic INPUT_ALIGN_YARM states, but the ALIGN_IFO guardian always failed in PREP_INPUT_ALIGN_YARM. So we skipped it for today. - MICH_DARK: we just used MICH_DARK_LOCKED, and tweaked the BS by hand. - Then we started full locking and had no problem getting to RESONANCE. ITMY IR and AS cameras are now centered as well. - We then manually stepped through CARM_TO_ANALOG until line 1716, ALS-C_REFL_DC_BIAS','FM1','ON'. - Then our day was halted by an 8.2mag earthquake in Fiji. - Although we were not 100% sure what it does, we clicked the "Very Large Earthquake" button on the ISI SENSOR CONFIG screen. So we probably will have to set the ISI back to where we want it tomorrow morning.
