Here the status of the dither alignment or c1ass:
- Both pitch and yaw centering on ETMY/ITMY were closed simultatenously with ugf of ~1/30 Hz.
- I made a medm screen with beam positions as measured by the dither system.The snapshot is attached. There are visual perimeter alarms (red box around the display) to warn about arm power being low or the dither lines not being on. The screen has a pull down menu with 4 scripts:
. assUp - sets up the gains, phases and matricies for the dither system (both the spot centering and the input beam alignment)
. assOn - turns on the dithers and servo - just the Y-arm centering part at the moment
. assOff - turns off the servo and dither lines
. assDitherOn - turns on the dither lines but does not turn on the servo
- All scripts are in scripts/ASS and the medm screen is in medm/c1ass/master/
Still to do:
- Commission the input beam and X-arm servos
- Make scripts for X-arm |
