HAM1and HAM2 Annulus System Update

(Jordan, Owen, Jake, Gerardo)

The annulus sytem for HAM1 and HAM2, shared volume, was pumped down initially with a single aux cart (Hi cube), then to speed thing up a second aux cart (another Hi cube) was added via the HAM2 AIP port.  After a couple of days the ion pump controllers appears to be able to keep up with the pressure, see attached trend plot.
