= 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. Calculate the needed resonant frequency.
 * 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
 * change to use a fused silica baseplate with optically contacted mirrors
 * Our current Piezo-Jena mounting system makes leak-through beams un-dumpable.  This really
 . really sucks for beams in the dark port.  We should put black glass in a "sandwich" style behind
 . the optics.
 * DON'T use Kapton tape in vacuum
 * If you are mad, Steve,  don't work on the optics.
 * Scan picomotors before assembling equipment using them.
 * Don't put any stress on the pins of a vacuum feedthrough (this affect DC photodiode design)
 * Put a temperature sensor inside the DC diode electronics nipple
