Abstract
| Advances in the performance of low and high temperature superconductors enable the development of advanced magnets for a range of applications, including tokamaks for fusion energy, dipoles and quadrupoles for hadron colliders. The capability of testing prototype cables and insert coils at high field is critical to these developments. We present here the conceptual design of a test facility dipole with features suitable to support the advanced magnet development efforts of both Fusion and HEP communities. A background field of 15 T is provided over a homogeneous length of 1000 mm and the clear bore of 144x94 mm can accommodate large fusion conductors as well as prototype coils for high field dipoles. Two technical solutions are considered. The first uses a forced flow Cable-in-Conduit Conductor and follows the design developed by EFDA for the EDIPO magnet. The second uses a bath cooled Rutherford cable and follows a block-coil design similar to the CERN FRESCA2 dipole, and the LBNL HD and LD1 dipoles. Following a comparison between the two approaches, we present two designs for the Rutherford cable approach including performance objectives, key parameters, and preliminary magnetic, mechanical and quench protection analysis. |
