More Diagonal annulus leak sorting
Kyle 

HAM11/12

Gerardo and I had improved things Friday but the rate of rise is still too high when the pump carts get valved-out today -> Using large forces applied at great distances, I encouraged all (160) ea, 7/8-9 obstinate door bolts that, in fact, more clamping was possible (~ 11/160 were very loose although at random not necessarily adjacent to each other - Friday Gerardo and I had done only the non-door bolts connecting the HAMs to each other and to the OMC spool - time ran out)

Attached data is promising. 

BSC4 

BSC4 annulus has a "high gas load" as well -> After Gerardo had reminded me that the dome had been removed during the "gutting" of the 2K, I put a wrench on a few of the bolts that I was able to access from the ladder nearby -> most of the bolts were quite loose -> We will torque these tomorrow during maintenance day.
