Apparatus-
Each HAM6 support tube bellows bagged (hermetically sealed) to encompass the large conflat joint and bellow's convolutions but not the small conflat joint -> 3/8" i.d. x 5' long exhaust tube (penetrating bottom of bag) -> Supply of helium to the top of the bag -> Applied 90 seconds of helium pressurization/flow per bag such that each bag remained inflated (like a balloon) and with confirmed/noticeable flow out of the exhaust tube -> Leak detector backing HAM6 turbo via series combo of (4) each 1.5" x 3' flex hoses

HAM6 volume = ~7,500L  
Net pump speed for helium > 500 L/sec  
Indicated helium baseline at start of testing < 1 x 10-10 torr*L/sec

Results-
SW bellows and big CF joint -> OK 
NW bellows and big CF joint -> OK 
SE bellows and big CF joint -> OK 
NE bellows and big CF joint -> inconclusive -> large signal response -> need to reverse order of testing and pressurize this bag with air while applying low flow of helium the corresponding small conflat to rule it out then test bellows convolutions separate from the big conflat joint

Will continue tomorrow
