  • etc
• 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
