Vent planning for Fall 2021


Clean Room SUS Work

Overall Requirements

List items you need before completing this whole section

  • Clean 3"->2" optics adapter parts (Side blocks, balance weights, mirror clamps)

  • HeNe Laser

  • Suspension Wire
  • Dummy 2" mirror
  • The mirrors that actually go into the vacuum.

Specific tasks and details

Gluing / SUS building [Oct 4 to Oct 11] (YD, JV, TE)

Requirements:

  • Dumbell+magnet assemblies need to be glued onto the optics adapter. 4 on the ring and 1 on a side block for each SOS.
  • One last round of dumbell+magnet gluing.
  • Testing of bond strength of last dumbell+magnet batches.

Estimated time: 3 Days

Suspending [Oct 4 to Oct 11] (YD, TE)

Requirements:

  • Need to push a few already clean Viton tips into 1/4" screws to be used as EQ stops. Assemble those EQ stops onto the SOSs.
  • Suspend dummy mirror for balance testing.
  • Balance the dummy mirror using the HeNe laser. Adding and moving weights for adjustments.

  • Suspend and balance actual mirrors that go into the vacuum using what we learned by experimenting with the dummy mirror.

Estimated time: 2 weeks
