Alexa, Daniel, Sheila, Stefan From yesterday: - We re-entered and re-focused the ITMX Green camera (#22). The picture is now good enough for feed-back use. - Updated the camera config file (attached). Today: - Updated the CAM.mdl library in isc/common/models/ - it had normalized and non-normalized inputs switched. - SVN Committed revision 9393 - Dave's script now copies the camera values into the H1:ALS-X_CAM_ITM_PIT_POS and H1:ALS-X_CAM_ITM_YAW_POS fields (see alog 15587) - With the X Green WFS running (feed-back to ITMX and TMSX, auto-centering running) we engaged the feed-back loop to ETMX, relying on gain hierarchy through the WFS loops. - All this seemed to work fairly reliably, although the WFS and camera gain are extremely low - it takes about 3 minutes for pulling in the alignment. - With that in place, we did a from-scratch baffle-PD alignment of the whole X-arm, and noted the Green ITMX camera position: PIT: 236.78, Yaw: 354.8. For this we used the following script: asc/h1/scripts/ditherAlign.py TMSX - All medm setting are shown in the attached snapshot (the PIT and YAW output matrices are identical). Tweaking that could still be done: - Fine-tune the output matrix - in particular the DoF3 (camera path) should be set to move all 3 optic in the right way - this would avoid having to go through a gain hieararchy. - Increase the loop UGF: main pendulum notches are needed to avoid a 2nd unity gain crossing.
