The induction heater with DC high-temperature superconducting (HTS) magnetization coil is a promising device for aluminum, copper and brass extrusion billets. Compared with an energy efficiency of just some 50% for conventional technology and limitations in processing speed, the energy efficiency of the HTS DC induction heater increase to more than 80%. The HTS DC magnet with its refrigeration...

In 2018 a new cryostat designed to support operation of a helically-wound-coil superconducting undulator (HSCU) was installed at Argonne National Laboratory’s Advanced Photon Source (APS) synchrotron. Magnet temperatures are maintained near 4.2K by natural circulation of liquid helium (LHe) through the magnet potting, and although the HSCU cryostat operates in “zero boil-off” mode by providing...

The international Facility for Antiproton and Ion Research FAIR is currently under construction at GSI, in Darmstadt, Germany. The core component of FAIR, the superconducting SIS100 synchrotron with a will operate with a high repetition rate of up to 1 Hz. The SIS100 ring with a circumference of 1083 m contains 108 main dipole magnets with a maximal field of 1.9 T. The ion-optical lattice of...

This paper presents results on a design, fabrication, and test of rotor cooling system for a 1-kW-class high-temperature superconducting generator (HTSG). This HTSG technically employs an HTS contactless power supply (CPS) to excite HTS field winding. The rotor of HTSG consists of HTS single pancake coils for field pole and HTS strands of CPS’ rotor. They are directly bathed and cooled...

A new terrestrial gravitational wave detector, Superconducting Omni-directional Gravitational Radiation Observatory (SOGRO), has been proposed in 2016 and seen as a competitive candidate of middle-frequency gravitational wave detector. In this detector, there are three pairs of 5 ton low-temperature superconducting test masses, which are separated by 50 meters and magnetically levitated by...

Quench protection is a major issue for HTS magnets that operate at high current densities with high stored magnetic energy. Quenches do not propagate rapidly in HTS coils and these coils heat up quickly because there isn't enough copper in the conductor. In addition, the conductor critical current and the engineering critical temperature will vary depending on the field orientation within...
