Sheila, Fil, T Vo

We got a little time at the end of PEM injections to try a different method of disconnecting the ETMX ESD cables.  We had the sheildling box already installed at EX, so we went there and first disabled the HV ESD driver, then powered off the low voltage driver.  Fil grounded the sheilds of the ESD cables using the grounding box, and then disconnected the LL cable from the shielding box (on the chamber side) and connected it to the grounding box he made on monday.  The interferometer stayed locked and the noise didn't change, but just as we were touching the cables on the input side of the shielding box the interferometer unlocked.  It seems like something is extremly touchy here, which we already knew.
