 GMW
standard Electromagnet Coils are designed for high
reliability and high fields at modest power consumption.
They are wound from precision slit, high conductivity
copper with mylar interturn insulation and a fibreglass
outer wrap. They feature separate aluminum heat sinks
with integrated copper cooling tubes. The complete coil
assembly in then vacuum impregnated with epoxy resin to
produce a void free structure that will not degrade under
continuous or cycled operation at maximum power dissipation.
Protective overtemperature switch interlocks are mounted
on all heat sinks.
