This morning, the vacuum responded to shutting of the water of the heat shield circuit (leak rate without pumping leveling out). The vacuum chamber was
vented and the heat shield with flexible lines was replaced with another heat shield with fixed lines. The chamber was again pumped down and water opened
at ~150 mTorr to test the leak up rate without pumping. No leaks apparent, so continued pumping down with turbo pump. At a vacuum of about 1E-6 Torr the |
