Summary

The primary objective is to re-glue the fallen-off magnet on ETMY. While we have the main volume vented, we could use this opportunity to do the following, keeping in mind the limited personnel availability.

1. Clean ETMY.
2. Best effort to put ETMY back in and reduce the required YAW slow bias voltage (so we can maybe use this as the testbed for the HV coil driver circuit).
3. Bypass the in-vacuum OMC and recover the full AS beam power for use on the AP table. Also, extract the copper OMC and DCPDs. This would likely help commissioning, the added complexity is that we have to remove an extra door.

Inventory required for re-gluing magnet and re-suspending optic

1. Magnet re-gluing fixture.
2. EP-30.
3. Spare wire clamps for re-suspending optic in cage.
4. Suspension wire.
5. Clean torque allen ball driver to tighten (but not over-tighten) SOS wire clamp.
6. Acetone to remove the magnets in preparation for re-gluing (do we need to take the remaining magnets off first? or just re-glue the one that fell off?).
7. Glass container and teflon pieces to soak optic in if removing existing magnets is necessary.

8. HeNe + QPD to check pitch balancing once optic has been re-suspended.

9. CDS infrastructure for testing optic diagonalization once we have re-suspended the optic.

Inventory required for optic cleaning

1. Spectroscopic grade methanol, isopropanol, acetone.
2. First contact kit (F.C., brushes for application, clean glass containers, acetone, Peek Mesh, green flashlight, tweezers/scissors).
3. Camera.
