Report of work (*:responsible person)

• VAC: *Kimura
  • One of the small leak was found where it was, but another large leak seems to exist. Leak hunting will last today.
  • There are 3 ways;

    • Leak location will be found and fixed without vent. -> ETMX gate valve will open, no delay.

    • Leak location will be found and not fixed without vent. -> Vent on Wednesday and Thursday, fix leak on Friday, pump down on Friday. -> ETMX gate valve will open, delay for several days.

    • Leak location will not be found and not fixed. -> ETMX gate valve will not open, no delay, but it will be difficult to find beam at ETMX.

• ETMX: *Hasegawa
  • TF for MM coupling of photo sensor was found.
  • RMS motion seems to be OK if the mirror is not kicked. Even if the mirror is kicked, damping speed is ~10min or something.
• ETMY: *Nakano, Shishido
  • Yaw dampins seems to be OK. Coupling between pitch and yaw exists. After ~10min or so, oscillation starts up to 10urad.
• IFO: *Enomoto, Izumi
  • Trial lock of Michelson did not succeed because of too much motion of ETMY.
• BS: Eleonora, Izumi
  • We are optimizing diagonalization of L2P filter. Needs more time.
• DGS: *Yamamoto
  • Interface card for PCIe on k1ioo was exchanged and connection between RTPC and IO chassis was established again.

Work plan (*:responsible person)

• IFO: Enomoto, Nakano
  • Damping, BS L2P, restoring alignment.
• VAC: *Kimura
  • Identifies the location of leak.
