After Kyle attempted to tighten HAM 11 and 12 south door bolts (they were already tight) last week, I leak checked the annulus again. Leak is still e-5 Torr-L/s of He range on HAM 11 south door. I didn't thoroughly check HAM 12 door again since background was high. Last week it measured e-7 Torr-L/s of He range. Connected aux cart and leak checker with hung turbos to HAM 11 and 12 and approached ~1e-5 Torr by noon. HAM 11 AIP still read overpressure with aux cart assistance. HAM 12 AIP read 6 mA range with assistance and 7 mA with aux carts valved out. I turned both AIPs off to preserve them, until we can vent the diagonal to remove and repair the door seals.
Looks like we replaced HAM 11 AIP in May AND Nov. 2016?!
