Quantitative Calculation of the Adiabatic Stability of REBCO Annular-plate for a Bitter-like HTS Magnet

REBCO coated conductors have outstanding performance in large scale applications. This paper investigates the adiabatic stability of a Bitter-like HTS magnet, which is stacked by REBCO annular plates and insulators with same inner and outer diameters interactively. In the model, this HTS magnet is magnetized by flux pump, and the induced screening current in the annular plates are equivalent to the superposition of concentric ring circuits. We calculate the flux change under heat disturbance, and investigate its adiabatic stability at different size and operating temperature. The anisotropic character of the critical current of REBCO is considered in the simulation.
