Summary Report

Type-A

Type-B

  • We inspected SRM payload and chamber and we think we can exchange the small mirror after the installation of the mid-size baffle. When are we going to change it?

  • In SR3, we locked the suspension and First Contact was applied.
  • In the corresponding filter bank, I updated the information of the transfer function of the new geophone.

Type-Bp

  • In PR3 and PR2, we tested the Traverser limit switches.
  • In PRM, OSEMs H2 and H3 were close to the end of their linear ranges, therefore, we moved them. The payload is not as stable as we would've liked, and was disturbed when we installed the Traverser limit switches. See klog.
  • Health check of PRs.
