NOTE: PROVIDE COOLING FOR MAGNET, COMPRESSED AIR OR NITROGEN AS
REQUIRED.
Additional Notes (continued):
2.
Superconducting magnets use liquid cryogens (helium and nitrogen). Due to quenching and to prevent
explosion due to overpressure in the magnet, excess pressure is relieved through rupture discs. Discharge
from these discs must be relieved to the outside through vents. Also, a separate emergency exhaust system is
required with a minimum of 12 air changes per hour to exhaust above the roof any accidental gas spillage inside
the room. The emergency exhaust system shall be activated by an oxygen sensor. Also, provide emergency
make-up supply air from the normal supply system whenever the emergency exhaust air is activated.
3.
Some manufacturers do not recommend blowing air directly at magnets.
