Drawings of the frame in the OMC chamber
Notes
- Miyoki-san suggested to use an uninterruptible power supply for the omc laser (10/12)
- Akutsu-kun suggested to simply remove a blank flange instead of installing a viewport for the laser injection; Saito-san agreed (10/12)
- One of the feedthrough flanges on the OMC chamber is not tightly connected as there will be one more cable connected to it for a picomotor (10/16)
- The feedthroughs cannot be directly connected to the KAGRA Dsub cable; there should be a gender changer inbetween (10/17)
- We moved the Optical Table B (POS table) out from the OMC area; it will be moved to the BS area on Nov 8-9 (10/31)
- PD/QPD in-air cables should be relocated so as to have the female connectors to the feedthrough (11/1)
- Piezo Driver setup is supposed to "1001" but was "1000" by accident, which means the input voltage was +/-2.5V instead of +/-5V (11/7)
