Session V: Thermo-hydraulics and cryogenics
- Arend Nijhuis (University of Twente)
The high Tc superconducting (HTS) tri-axial cable fits long-distance power transmission rather than the 3-in-One superconducting cable, since the tri-axial HTS cable has low ac loss and large cooling channel, and the tape length used for a cable is much shorter. We investigated a suitable cable structure of HTS tri-axial cable with counter cooling by liquid nitrogen for long-distance power...
Abstract
The new HTS design concept for the DEMO toroidal field (TF) coil, based on cross-conductor (CroCo) strands, has been proposed by KIT. The coil is layer wound and consists of 12 layers with different jacket radial thickness grades. The present work is focused on the thermal-hydraulic analysis of the conductors’ design, which includes: 1) hydraulic analysis—calculation of the mass...
Most of the large fusion devices like W7-X, JT-60SA and ITER use or will use High Temperature Superconductor (HTS) current leads (CL). In all cases the HTS material Bi-2223 embedded in a AgAu matrix is used. In the meantime, laboratories worldwide are investigating the design of a high current HTS CL composed of REBCO. The Karlsruhe Institute of Technology (KIT) has developed a 20 kA HTS...
