2025 April vent - VAC diary
Today's activities:
Feedthru installation on HAM1 was completed. An electrical issue with one of the 25-pin feedthrus on the D1 5-way cross and/or in-vac cable means this port will be revisited after ISI installation. Electrical testing is ongoing for the new feedthrus/cables.
BSC8 annulus system is being pumped by aux. cart.
CP1 RGA is being pumped down for initial commissioning.
Flange protection was added to the HAM1 top 16.5" port.
