* Lab in-personnel: Himangshu, Ping

1423	Turbo on IVC = 12 nbar. With Turbo valved out for 1 minute, IVC = 160 nbar.
1518	Connected the CVJ to the turbo line, pumped out with the scroll pump first. Tried to switch over to the turbo but it was failing. Pressure was above 1e-1 mbar when we opened up the CVJ port, so pumping with the scroll pump for a while until the pressure goes down below 1e-1 mbar. Keeping the CVJ on the turbo overnight, IVC valves are closed. CVJ pressure is: 8.6e-3 mbar. Will do the cryocleaning tomorrow.
