Preparation for O4

Many portable accelerometer to chamber and beam ducts
- Checking the vibration effect from vacuum pumps
- Evaluating the effect to OMC leg
- Remove after hammering test
Finalize the PEM installation
- Accelerometer to C chamber and TMS table
- Microphone to C chamber
  - Do we need both booth and field?
Investigation of the PEM injection is just started
- Acoustic injection preparation
  - Output sound smaller compared from O3GK's
- Magnetic injection
  - After O4a?
Voltmeter preparation
- We made the PEM channel
