Influence of dump voltage and allowable temperature rise on stabilizer requirements in superconducting coils

The authors present some simple relations between the dump voltage and the stored energy, temperature rise, and coil geometry that are useful in scoping the required amount of stabilizer. Comparison with some recently proposed fusion magnet system designs indicate that excessive dump voltages could result in some cases. High-temperature superconductors may require more stabilizer than the conventional alloys. Calculations with simple model coil systems indicate how tradeoffs between between various coil parameters affect the dump voltage.<
