Convection (CvH).


Convection (CVH)

  • Current: 100-30 kA
  • Coolant: LHe + GHe

The CvH is a convection type, LHe + GHe-cooled current lead. It has, similarly to the CdH, the cold terminal immerged in a bath of liquid helium. In addition, the helium gas generated from the boil-off is funnelled into one or several channels inside the current lead and the gas is used to cool the current lead from the inside. This is a very efficient design compared to the CdH, as it takes advantage of the helium boil-off. This design is used for operating currents ranging from 100-30 kA.
