#pragma section-numbers off #pragma section-numbers 2 = 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) * Adapter rings, wire clamp, wire block and retainer rings are all clean on the flow bench * Waiting for machined balance masses from RDL ETA ~1 week * All hardware except 8-32 Helicoils are cleaned and ready for assembly, eta on Helicoils ~1 week * HeNe Laser * Suspension Wire (wrapped and stored in the clean room) * 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. * for the side magnets, we need longer assembly to avoid interference with the clamping screws. -> an additional magnet will be glued on a magnet-dumbbel pair. Estimated time: 3 Days * Assembly drawing ~75% complete, will be ready 10/11/21 ==== 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. * Suspension order of optics and origin of the optics: 1.
