 * TF of MCe had a shift of peak frequency on pitch. Ushiba-kun will measure it again with the well-centered oplev. It will be reported at the recovery meeting or later.
 * All others should be OK for closing IMC chambers.
  * The resistance of the Coil of MCo H4 looked high. Washimi-kun will measure it again on Monday, but it won't stop closing anyway.
  * Washimi-kun will measure inductances again on Monday.
  * Check no dust inside, especially on the bottom before closing.
  * Check the leak points are fastened tightly when closing.

IMC recovery(20240322)



one of templates for IMC closing by Akutsu-kun in 2021.


Summary


  • TF of MCe had a shift of peak frequency on pitch. Ushiba-kun will measure it again with the well-centered oplev. It will be reported at the recovery meeting or later.
  • All others should be OK for closing IMC chambers.
    • The resistance of the Coil of MCo H4 looked high. Washimi-kun will measure it again on Monday, but it won't stop closing anyway.
    • Washimi-kun will measure inductances again on Monday.
    • Check no dust inside, especially on the bottom before closing.
    • Check the leak points are fastened tightly when closing.
