I used a Mass Spec 47-J5. It had been jostled in shipment so I had to rebuild it first. B/C of the rebuid, I was unsure of the validity of the 47-J5 readings.
That's why I used the Snoop. Yes, it was a big leak. We were losing 2% a weak, and the pressure was usually staying at the 4 psi spec.
The pressure builder was working hard to keep the pressure at 4 psi, as designed.
The leak, however, was working hard to empty the Helium. Good thing the mag wasn't at field.

Didn't Intermagnetics actually make that magnet?

the leak is big enough to detect with snoop? that's rather huge. What leak detector did you use?
