Beam Tube ion pump coupled to port hardware at Y2-8
Kyle, Gerardo Today we coupled the ion pump to Y2-8 -> The operation was slow and meticulous but we feel confident that no new net forces are realized by the beam tube nozzle -> We also pumped out and leak tested -> Still to do is the pulling of the HV cable and bake out -> In the meantime we will likely move on to X2-8 and repeat the exercise. (Note that Mike Z., Ken Mason and others provided the components used)

Upon reconsideration the BT valve is experiencing a minimum of 55ft*lbs as a result of having mounted the 8" gate valve to the reducing Tee before having coupled the ion pump to the 8" valve
