Discussion item
Start the investigation for measurement of the newtonian noise : NN meeting (URL)
- Portable water fluid monitor
- Simulation
- Infrasound monitors
Start the discussion about KAGRA seismic motion (URL)
- Share the information and discussion using the timeseries and spectrum plots
- Interesting measurement
- Tilt meter (Do not need because underground experiment?)
- Share the information between Tilt meter measurement at SK area
- Trun over seismometer analysis from Fujikawa-san
- Magnetic field
- Arrived four magnetometers at 17th Mar.
- First data taking at end of March with GERD
- New collaboration about KAGRA PEM
- We are investigating this issue
- Also, discussed previous PEM meeting
- Call the collaboration(Both KAGRA collaboration and just the collaboration)
- If you know the interesting laboratories, please contact to us.
