Preparation for O4

• Discussion of the portable PEM channels

  • klog24621

  • Still under investigation with the results of the tapping test
• Finalize the PEM installation
  • Accelerometer to C chamber and TMS table (Maybe postpone after O4a, lower priority)
  • Microphone to C chamber (Maybe postpone after O4a, lower priority)
• Investigation of the PEM injection is just started
  • Tapping test is higher priority
  • Acoustic injection preparation
    • Output sound smaller compared from O3GK's
  • Magnetic injection
    • After O4a?
• Voltmeter preparation
  • We made the PEM channel
    • K1:PEM-VOLT_{PSL,IMCREFL,REFL,ISS,AS}_TABLE_{GND,FLOAT,DIFF}
    • K1:PEM-VOLT_OMC_CHAMBER_{GND,FLOAT,DIFF}
  • AC power monitoring
    • Bought transreducer
    • Prepared
