Pump down in the conditioning station started at ~2:40 for rough down. The turbo pumps were turned on at ~3:30 and at 3:52 the pressures were reading as follows:
IMG in the containment box 9.2 x 10^-5 T
IMG in the secondary 2.0 x 10^-3 T
ION in the service cap 4.6 x 10^-5 T
Note that the cross has been installed on the vacuum vessel which now includes a turbo pump and the IMG 100.
Leak check will occur tomorrow. |
