CVJ was not pumped out and had exchange gas from last warmup, so connected the CVJ with scroll first and left overnight for turbo pumping.
On monday, found turbo failed. There must be some outgassing in the CVJ. So kept pumping with scroll again and tried switching to turbo, but it was failing.
We have reached the pressure range at which we need the CVJ to be ready. Turbo is not failing with the IVC luckily. Kept the turbo on IVC overnight.
Ping did another cryoclean yesterday. Refilling LN2 dewar and preparing for LN2 transfer.
