Summary of the week ending July 31st. Number of elog entries = 53
- SUS
+ ETMY-LR sensor looked strange. Something wrong.
+ Responses from the DC alignment bias to the shadow sensors and the oplevs were checked.
--> ETMY shows the response with the opposite sign. Wired.
+ ETMY shadow sensors were examined in terms of the spectra.
--> WF, AA and ADC noise looks reasonably low and not high enough to explain the low frequency noise.
+ Adjusted all the OSEM gains
- LSC
+ MICH noise budget is ongoing. WF filter needs to be greater than 21 dB to have dark noise of the PD greater than ADC noise
+ The arms became lockable
- CDS
+ modified and re-ran activateDQ.py.
+ c1iscex crashed for unknown reasons and we physically rebooted it.
- ALS (Fiber experiments)
+ PMC trans is sampled for the fiber beat-note measurement on the PSL table.
+ The beat-note signal between PSL and X end laser were obtained.
+ Some optics in the ETMY table were rearragend to have the Y green light aligned.
- ACS / ASS
+ incident beam axis has changed a lot.
+ X arm and Y arm ASS were reactivated.
---> The sign of some of the control gains had been wrong.
+ The incident beam axis and X/Y arm were re-aligned
- IOO/MCWFS
+ Some medm screens fixed.
+ Adjustment of the demodulation phase on each quadrant on WFS1 and WFS2 are done.
+ The sensing matrix (from optics to WFS sensors) were measured.
- OAF
+ c1pem was modified
+ plugged a seismometers to ADC through an AA board.
--> channels are coming to the digital land
- Preparation for the invac work
+ 7 pieces of beam traps are available
+ Tolerance of the arm length is estimated to be +/- 2 cm.
- PSL/RefCav
+ ABSL is injected into the reference cavity. some flashing happened but no locking.
+ eddited the psl.db file to set EGUF and EGUL
+ turned RefCav heater and servo back on
