(Jenne D, Corey G, Jeff K)
From Niko's handoff, we knew there was (1) communication issues with EY (so this would prevent locking EY), and (2) Both green arms looked clipped from their video.
So one of the first things we thought we'd try is running a baffle alignment script....I later found that this is more correctly called a Dither Align script. Jeff called Jenne to get info on how we can do this.
[Side Note: TJ has plans to get baffle alignment into guardian.]
Ran Dither Align (i.e. Baffle Scripts)
- Dither Align scripts can be found off of new INIT_ALIGN window (sitemap/ASC/Init align).
- In preparing to run these scripts, we used Jenne's ndscopes templates located at: /ligo/home/jenne.driggers/Templates/Scope
- file names: BafflePDs_X[Y]arm.yml
- Order of operation was to work on suspension one at a time:
- Misalign ITMx & ETMx (make sure TMSx aligned)
- Run TMSx Dither Align script which is on drop down for Xarm on INIT_ALIGN window (when script done, it doesn't say anything like "done" or "complete", and terminal stays open. But you'll see terminal no longer doing anything as well as no action on ndscope). When it looks complete, move to ITMx...
- Align ITMx & run ITMx script....when it looks complete, move to ETMx
- Run ETMx script
Unfortunately, after completing the ETMx script, we did not see any light in the ALSx camera!
At this point, Jeff took ETMx to its slider values (not oplev, osem values, etc!) to an earlier time, and finally we had light on the camera, and X-arm eventually locked after some quick alignment tweaks!
