GV6 annulus ion pump (AIP) replaced
Today, Gerardo replaced the annulus ion pump body for the GV6 annulus system. He then handed off to me to hook up the turbo/aux. cart. The pressure at the cart was ~3e-5 after 4 hours of pumping.
There will be a pump cart running at GV6, at the Y-arm termination slab, until the ion pump transition pressure.
Transitioned to ion pump successfully. Aux cart and turbo were removed.
