American Magnetics Current Leads for Cryogenic Systems Brochure - Manual (Page 5)

In bucket dewar systems
the magnet support
stand is designed to
accommodate either fixed
position or retractable
current leads. In bottom
loading dewars or cryostats
with room temperature
bores the dewar itself
supports the magnet and
integrates the current
leads into the design.
Model of typical liquid helium
cryostat with vapor cooled leads
and series superconducting bus
bars installed on magnet
support stand.
