Thanks to all who responded - I was OK with the liquid to gas calcs (OK,
I was a little rusty) but I did not know what the volumes in a 400 were.
Appreciate the help with the calculations and holding volumes of
cryogens.

Does anyone know the volume of LHe and LN2 that are held in a standard
400 MHz magnet (narrow bore, with active shielding)? Our safety group
will not sign off for use until adequate ventilation is provided in the
event of a quench. As a result, I am trying to determine the volume of
gas generated by complete boil off of both LHe and LN2 from my magnet.
