Today's activities
Workers: Akutsu, N. Sato, K. Tanaka, Nakano
- All
Found that flanges of MCF and MCE chambers were not protected by white tapes although there were viton o-rings on. We protected these by white tapes. -> Informed this to SEO already.
- MCi
- Relocated the connector plate.
- Attached adapter structures for black shields onto the pillars of the MCi suspension. (But not yet the black plates.)
- MCo
Found the connector plate on the MCo suspension was hard to relocate on the optical table in the chamber due to short wires from actuator coils.
- MCe
- Relocated the connector plate.
- Found the birmndy connector was loose!! Maybe VIS needs to check the other suspensions...
Before working, I (Akutsu) stopped the laser source for the tilt sensor; I did not know what was the proper process to stop the laser source, and I could not find any type number of this Thorlabs driver, so we could not search for the manual, so I just turned it off. Ashikarazu.
Next plan
- Wash some screws.
- Have VIS to modify the MCo connector.
- Have VIs to check whether the birndy connectors on the suspension structures are loose or not; at leaast, that for MCe is loose.
- Have VIS to consider how to tame/fix the electric wires from the coil actuators so that they won't cross the laser beams.
- Check the ghost beams.
Wanted!
- 2 metal rack shelves in the clean booth (each for MCF and MCE); the height must be lower than 180 cm due to lower ceiling of the relevant clean booths.
- 1 sticky mat to get the dirt off our feet.
