This morning we checked HAM7 annulus system pumpdown and the aux-cart displayed 2.6X10^-05 Torr, good progress so it appears to be doing good.  We disconnected the SS-500 cart from HAM6 turbo and connected it to HAM7.  We checked all ports were "nominal", detached the active purge hose and no blowdown was done, since we had the relay tube valve (RV-2) open, took advantage of this and we let the purge air purge HAM7 overnight out RV-2.  After closing RV-2 we started the pumpdown of HAM7.  The purge valve (all metal valve) and the roughing valve at the turbo assembly were closed at 3.0X10^-05 Torr.
Attached is a plot of the pumpdown thus far.
