HAM1 Passive stack out

Randy, Mitch, TJ, Jennie, Corey, Jim

This morning we pulled the rest of the HAM1 PISI. This part was relatively trouble free, masses stuck to the viton corks a bit, so we put a bit of tension on the chain bridle then tugged on the mass till it popped free. Masses, springs and hardware were kept clean, the support table and risers were set out on the floor. I think vac is up next with feedthrus, the ISI still has to be swapped to a different container in staging.
