2025 April vent - VAC diary
Today's activities:
GV7 was soft closed to facilitate leak checking of the X beam manifold.
The X manifold Turbo station was spun up and valved into the volume.
BSC8 annulus is still pumping. We attempted to swap it to ion pump only pumping, but it didn't hold long, so we valved the aux cart back in and will let it pump overnight before trying IP only again.
CP1 RGA bakeout has commenced.
HAM1 replacement gauge has arrived, but was poorly packaged, so it will be tested in the EE lab prior to install.
