This morning I vented IP11 (again!) with bottled N2 and then Mark and Tyler bolted it to the new IP11 valve. The chevron baffle housing was already attached to bottom of IP11 from leak testing yesterday (baffle housing SN002 is leak free). I leak checked the bottom flange of new IP11 valve and also the new HV NEG housing/valve on BSC6, with background <1e-9 mbar-L/s. No leaks detected. Later Kyle leak tested the flange connecting bottom of baffle to top of IP11 valve. No leaks detected. EY main turbo is valved back in and good to go for in-vacuum high voltage.

We left a hung turbo pumping on IP11 overnight, backed by leak checker.

BSC10 turbo cart is also valved in with AIP ON.
