  • Remote participants by eZuce: None
  • Report of work (*:responsible person)
    • Alignment and ETMY: *Izumi, Enomomoto, Ushiba, Elenora
      • Photo sensors was investigated and it was turned out that the satellite amplifier has an oscillation above 10kHz. Capacitors were added, then the oscillation went away. All the satellite amplifier should be modified.
      • It was turned out that the glitch at the ETMY comes from DAC. DAC output has sometimes zero voltage for 100ms~1s. IO chassis will be replaced.
