Today we swapped the 75 l/s ion pump used for the annulus volume on the Y-Beam Manifold (YBM) . Annulus volume was isolated and the pump swapped, no issues encountered during the swap.

An aux cart was used to pump out the ion pump body before switching the IP on. After a couple hours of pumping with both the aux cart and the IP, the aux cart was isolated and the IP was able to maintain the pressure.
