Our vision to design and build reliable HTS magnet which will meet your fusion system specification. Our technology will make the best use of HTS REBCO conductor high current density with no-insulation winding approach, but specifically optimize turn-to-turn resistance to reach acceptable ramping time and long term operation requirements. Our core technologies:

(1) In-depth understanding of REBCO materials, microstructure, critical current field and temperature dependence Ic(B,T)

(2) Long time experiences in magnetic simulations and analysis, particularly for large scale magnet systems with multiple coils.

(3) Multiphysics simulations for system design and optimization, including Electrical, Magnetic, Thermal and Mechanical. 

(4) Unique simulation and analysis capability for No-Insulation HTS REBCO Coil, particularly for ramping and discharging. 

(5) Intensive superconducting coil instrumentation capability with fast and normal DAQ sampling rate, for coil characterization. 

(6) Experiences HTS tape coil winding capabilities for rectangle round corner coils, racetrack coils, and solenoids coils.

(7) High capability in cryostat and cryogenic design which will meet your system requirements. 

(8) We are small company, so our overhead is much smaller compared to the larger organization. 

(9) We believe that we have the recipe to manufacture high quality and functional HTS coils/magnets.

Relationship between winding tension and as-wound coil stress (hoop & radial)

Optimize winding induced tension in wound coils by changing winding tension Back tension motor control, 10%, 20%, 30%, 40%, 50%, 60%, 70% Winding pressure 6.9 MPa, 13.8 MPa, 20.7 MPa, 27.6 MPa, 34.5 MPa, 41.4 MPa, 48.3 MPa,

No-Insulation REBCO coils are different from traditional insulated coils.  An equivalent circuit model are needed to characterize the tangential and radial current the coil winding pack, particularly during ramping . 

We will design and simulate specific cable for the customs needed magnets.
