HAM1 Pumpdown Update

Pumpdown continues on HAM1 and it is progressing.  The chamber is currently being pumpdown with the SS500 cart aiding the turbo pump up on top of the chamber.  We are very close to opening the ion pump for this chamber.  Vacuum pressure is currently at 8.95x10-07 torr.  The aux carts to pumpdown the annulus for both chamber HAM1/2 were disconnected Monday, see aLOG entry 89440.
