  • 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.
    • 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 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.


  • 2 metal rack shelves in the clean booth (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.
