ReCon TM Magnet Systems
Based on heat load and size of the superconducting magnet
either a dry conduction cooled or ReCon
TM style geom-
etry is recommended. ReCon TM style magnet systems use
cooling power of a closed cycle 4K cryocooler to recon-
dense gaseous helium back into the liquid Dewar. The
evaporating gas is liquefied in a thermodynamically ef-
fective manner and the cryocooler is strategically located
in the Dewar. The first stage of the cryocooler is used to
cool the shields of the Dewar thereby eliminating the need
for any liquid Nitrogen. ReCon
TM magnet systems offer
combined benefits of traditional LHe systems with near
zero helium boil-off. These style systems are ideally suited
for retrofitting existing magnets and sample inserts into
a re-engineered Dewar with a suitable gas handling sys-
tem. Pulse tube cryocoolers are ideal for applications that
desire lower vibrations.
