Vertex turbo spun up

[Kyle, Gerardo, Chandra]

After 20 hrs of rough pumping over two days, we transitioned to turbo pump (0.6 Torr). Before we leave tonight we will transition from QDP80 backing to scroll backing and decide if we need turbo water cooling. Tomorrow we'll turn QDP80 off and leak check HAM2 conflats.

Pressure currently at 0.4 Torr.
