The Cryostat
General Description
The cryostat is of conventional design, consisting of a central
all- welded stainless- steel helium vessel, surrounded by a
gas- cooled radiation shield and liquid nitrogen reservoir. The
complete assembly is contained in a stainless- steel outer
vacuum vessel with two service turrets located on top of the
cryostat. The turrets provide access to the helium reservoir
for the demountable magnet leads, helium level probe, and
helium transfer siphon. The outer vessel has a bottom- flange
closure constructed from aluminium, which is sealed to the
main body, and bore- tube by compressed o- ring seals. The
system is designed to be shipped without disassembly to
facilitate quicker and easier installation.
