I was able to fix the leak on the 12" CF rotatable flange on the YBM turbo this morning.  All CFF joints on this unit are now leak tight (< 1.9 x 10-9 Torr*L/sec LD background/baseline). 

Gerardo M., Tyler G., Kyle R.

Opened GV5 and GV7.  Gerardo M. had decoupled the HAM5/HAM6 AIP pump carts earlier and I had valved-in HAM6's IP, isolated,the HAM6 turbo, spun it down and de-energized it but the connecting hose and controll cable still need to be removed.  This will require climbing up on HAM6 again tomorrow.  We intend to clean up our various work areas over the next couple of days.
