Additional Notes:
1. Utility requirements for magnets vary greatly among manufacturers. There are different kinds of magnets with
specific utility requirements. Requirements also vary if gradient power supply and gradient coils are used, and
whether they are air-cooled or water-cooled. A water-cooled system, consisting of a closed loop water supply with
water-to-water heat exchanger to a refrigerator type heat exchanger, is recommended for gradient power supply
and gradient coils. The water must be filtered to protect equipment. Provide domestic water back-up for cooling
water in case of emergency.
