GV 20 was closed and the main turbo pump at X-End was valved in to the main volume during the installation of IP12.  The chevron baffle volume was vented slow using UHP N2, as well as the IP body.

After Mark, Tyler and Chris were done installing the pump, the volume of the ion pump was roughed down to 1.0 torr using an aux cart, work will continue with this IP next week, since still needs to be pump down and leak tested.

After opening GV20, the main turbo pump was isolated, and shut down.  The aux cart flex lines remain connected to IP12 and the metal valve is closed at the IP.
