  • PSL44Hz
  • Can remove this effect. Move the 24V power supply to ouutside of the PSL room.

Portable1 acc moved to white laser lack.

  • ISS cover check
  • Check the portable acc, but not detected the serious noise, reject the candidate from optical table
  • Discussion about the lightning monitor at 12th Sep.
  • monitoring the MAX/MIN magnetometer time series monitoring
  • There are lightning candidate around the evening
  • Full sampling rate time series monitoring
  • correlation between BS oplev was observed only 5th Aug.
  • PEM injection T~e-9 but 5thAug is e-6 level
  • Need very large coil
  • If we use the frame, we can make larger magnetic field
  • Omicron was unstable now
  • Development the spectrogram tool
  • Enkaku injection project
  • IFIとPR2付近の真空ポンプの振動を調べた
  • PR2のドライポンプはそもそもノイズレベルが大きい
  • コントローラは確認したか？
  • Fujikawa+Mori
  • Extract the line peak
  • Implementing the various noises
  • Earthquake vs lockloss
  • check by the MCF seismometer
