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.
