In the desire to be able to do some repair and testing of podded seismometers I have retrofitted VBO A with a Neon calibrated leak, a LN2 cold trap, and a cold cathode pressure gauge. Unfortunately the LN2 cold trap uses a viton seal, so its two valves are to isolate it from the normal bake oven operations. Pump down should be able to begin tomorrow for leak checking and maybe even a test.
