On Monday, the -Y door went on the HAM1 chamber with some minor issues not noted on previous installations, for some reason we had two minor misalignments: one, the door did not hung parallel to the HAM's flange,small tilt towards the outside on the upper part of the door, maybe the pick point slid forward. Two, the door required a clocking move, we pinned two holes spanning 5:12 O'clock, then rotated the door clockwise a bit until all of the holes aligned, then a small movement on the -Z to complete the alignment about 1/8". After all of that the door looks pretty concentric to the chamber flange.
Something to note, a dirty glove was found inside the chamber, yes inside the chamber under the support tube on the -Y side of the chamber, as I write, I nod, because it does not take much time to get this dirty thing out of the chamber.
HAM1 +Y door was installed today after replacing the inner o-ring, which had fallen out during door removal.
O-ring install went fairly smooth, only popped out of the groove a couple times, but we were able to get it seated properly and continued with door install.
No issues encountered, and we started pumping the HAM1/2 annulus volume to confirm there were no door o-ring leaks. Currently both aux carts are at ~2E-5 Torr.
Update on annulus sytem
Pumping continues with two aux carts, one connected to each chamber (HAM1 and HAM2 annulus), last thursday we turned the ion pumps (see trend data attached), and HAM1 responded well, however the ion pump for HAM2 railed, after a couple of wake up hits it started working. Currently both systems are doing good, probably they'll be ready to run on ion pumps soon.
