HTS Dipole Magnet with a Mechanical Energy Transfer in the Magnetic Field

Abstract

There were designed and successfully tested at Fermilab several high temperature superconducting (HTS) model magnets for particle accelerators. Some of them worked in a persistent current mode continuously generating magnetic field in the iron dominated magnet gap. In the paper was investigated a novel HT dipole magnet concept with a mechanical energy transfer in the magnetic field. To pump the energy in the superconducting HTS dipole magnet used a detachable magnetizer. The HTS dipole magnet was build and successfully tested at a liquid nitrogen temperature. Discussed the magnet design, test results, the proposed approach limits, and efficiency.
