Conduction (CdH).

Sketch

Conduction (CDH)

  • Current: 10-100 A
  • Coolant: LHe

The CdH is a conduction type, LHe-cooled current lead. The cold terminal is immerged in a bath of liquid helium, which removes the heat conducted from the warm terminal (QC) and any heat generated from resistive losses in the current lead (QR). This design is used for operating currents ranging from 10-100 A.
