Retrofit (CvH/CvHNH).

  • Current: 2-30 kA
  • Coolant: LHe + GHe + LN2

The retrofit current leads are designed to fit into existing set-ups. It can utilize either the CvHH or CvHNH design to upgrade your existing current lead. Mark & Wedell is specialists in implementing new solutions in old cryostats taking spatial constrains into account. Such a retrofit can enable a current increase of up to 50% and/or a significant reduction in the LHe consumption. This in done by utilizing HTS material and LN2 as a coolant. This design is used for operating currents of 2-30 kA.
