# Convection w. HTS (CvHNH).

Sketch

• Current: 2-70 kA
• Coolant: LHe + GHe/LN2

The CvHNH is similar to the CvHH, but here liquid nitrogen (LN2) is introduced to cool the resistive part of the current leads (section 1 (see sketch)). When the design specification allows for LN2 to be used as a coolant, the helium consumption can be significantly reduced. This design is used for operating currents of 2-70 kA.
