Rai was able to inject ionized gas into the YEND station chambers today. It took about 15 minutes to reach 42 torr where we ended the experiment.
The chamber is roughing down again and will transition to turbo this afternoon.
Pirani gauge plot attached.
Y-End is now on turbo, CC is ON, pressure is at 1.34x10-06 torr.
Cooling lines open for the turbo.
It actually took 29 minutes to get to 42 torr, faster than I had calculated.
