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.
