Pumpdown was restarted this morning around 9:11 am local time.  After pressure inside HAM7 reached 0.5 Torr we switched over to the turbo, we had a very smooth transition.  After the internal pressure of HAM7 reached 5.0x10^-05 Torr all O-ring isolation valves were closed (we have one at the turbo pump, another at the chamber and one more at the relay tube).
HAM7 internal pressure after 12+ hours of pumping is 5.2x10^-06 Torr.  The attached plot has a small glitch at the 10 hour mark, likely due to the DAQ restart.

Annulus ion pump update.  The ion pump controller was turned on this morning, the ion pump controller struggled for some time as it was railed, but we did noticed that the pressure reading reported by the aux-cart (aux-cart remains connected and pumping on this system) dropped very slow, but after a some minutes the ion pump controller was not railed no more.
