VIS Meeting

Participants: Takahashi, Fabian, Mitsuhashi, Tanaka, Lucia

Summary Report

Type-A

  • Offloaded the F2 in EY. The heater on the cross tube was not effective for the F2.

Type-B

  • At the racks outside the clean rooms, we used screws to secure the connectors that use gender benders. We checked all other connectors also, outside and inside the clean rooms (mini rack).
  • I wrote a script to blend LVDT and geophones, based on Terrence's methods and tutorial. It's still a work in progress, but I might be ready to test the results in a suspension next week.

Type-Bp

  • We also checked the racks for loose connectors. We found very few loose screws, and we tightened them.

Type-C

Electronics

Control

Schedule

  • Type-A: Lucia will work with these suspensions today and the whole next week.

  • Type-B: Optimization of IP controls. Maybe testing the filters generated with Terrence's method.

  • Type-Bp:
  • Type-C: Finalization of the OMMT1/2/OSTM suspensions.
