Sheila, Elli, Dave, Stefan We spent some time to automate the transition to a CARM offset of 30ppm. In particular: - The DRMI looks ok with the new TCS settings. We did not retune the loop gains - that should probably still be done. - Noticed that with the new TCS central heating on ETMX the WFS loops in DRMI behave differently. - We increased the gain of PRM pitch WFS loop by 10 to H1:ASC-PRC1_P_GAIN = -0.06 - We increased the gain of PRM yaw WFS loop by 20 to H1:ASC-PRC1_Y_GAIN = 0.02 - We turned off the SRM WFS loops - they seem to be unstable with the new TCS heating. - We moved the transition to RF DARM to a setpoint of sqrt(TR_X+TR_Y)=1 (was 2). This seems more robust. - We tweaked the PREP_TR_CARM state to give the Beckhoff servo some time to converge - We rewrote the transition to CARM_TR in Guardian - it's now really smooth. - We added and commissioned the states RF_DARM, CARM_30pm, TR_QPD_TRANSITION and CARM_20PM. They do what was discussed in alog 15318. - The challenge is at the CARM_20PM step - it doesn't want to stay there fore too long... The only troublesome spot is the ALS_COMM CARM fringe finder. It often grabs the wrong one, and advances to DIFF before the serve setled. Definitely needs work. The the CARM reduction steps from DRMI_LOCKED to TR_QPD_TRANSITION worked twice in a row flawlessly.
