IP4 is back from rebuild and shipped under vacuum (measured mid e-5 Torr range). We pumped down with an aux cart, isolated the turbo, and then turned on high volts and measured 1.8-2 micro-amps at 7 kV on each channel. The pump is now vented with dry N2. Monday we will vent the blank on IP4's new gate valve, verify there is no leak into main volume, and then install IP4.
