| = 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? And Bigger? * always draw ALL the dogs for EVERYTHING * CVI mirrors coated for 45P don't get better than ~98% reflectivity |
