Vacuum opening Plan of Action
Next Generation DC Readout Notes
- Put the resistors on the PD block, not the nipple.
- Wider separation for the PDs so the ghost beam can get wedged out.
- Black glass ring around the PD cans to catch the 1st ghost beam.
- Black glass dumps all over the place for the leak throughs. Optic mounts should have their own dumps.
- Don't use any of the Piezo-Jena crap.
- Don't use copper for the OMC body. All fused-silica, all the time.
- Don't use a teensy mirror in the OMC.
- Make both curved mirrors on a OMMT movable?
- always draw ALL the dogs for EVERYTHING
