Summary Report

Type-A

ETMY

  • [Terrence] Tower control was implemented.
  • Guardian was made to go to ALIGNED state with MN OPTICALIGN offsets.
    • MN to TM DC control was implemented (Not posted yet).
    • I need to modify Guardian to engage this, but one of the photosensor is not working properly so there's no damping at the MN stage so I postponed this.
