Put RF into Chopper 2X, 2Y and Buncher cavities. Incrementally adjusted the forward power to previous GSET levels while monitoring Chopper vacuum. Chopper 2X gave us a few minor burps on the way. Resonance adjustments are not yet optimized so we will continue tomorrow or Friday.

We did our check list, turned off the ion pumps and started to flow gas. The ion pump at 1L11B tripped off at about 20 mTorr in 1L10. VIP1L11B was on the other side a closed beam line valve and it also has a turbo pumping on the ion pump. It tripped at 4e-6 Torr. We turned off the mass flow and stepped back. Pausing and seeking advice is a contingency that was in the procedures for just such an event.

Apparently the VBV1L11A has a massive leak. Frank Humphry and I discussed some options about what we might do. One of those options is that we do not process 1L10.
