Normal zone in large composite superconductors*
نویسندگان
چکیده
This paper considers the nucleation and propagation of a normal zone in large composite superconductors, considering the relatively tong time of current redistribution in the stabilizer. A model is proposed for treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and the temperature distributions along the conductor. Numerical simulations have been performed of normal-zone propagation for cryostable and non-cryostable conductors, and analytical expressions obtained for the velocity of propagation.

Initiation of traveling normal domains in large composite superconductors
We consider the initiating energy for traveling normal domains in large composite superconductors. We perform numerical simulations of normal zone initiation using the effective circuit model. The initiating energy is obtained as a function of transport current and four dimensionless parameters characterizing the composite and cooling conditions. We suggest an analytical expression determining ...
متن کاملPropagating normal domains in large composite superconductors
We study the nucleation and propagation of the normal zone in large composite superconductors, considering the relatively long time of current redistribution in the stabilizer. We propose a model treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and temperature distributions along the conductor. Numerical simulations are per...
متن کاملPropagation of the normal zone in composite superconductors with high contact resistance
The propagation of the normal zone in composite superconductors with high thermal resistance and high electrical contact resistance between the superconducting and the normal components of the conductor is analysed. It is shown that in certain conditions propagation can result from successive multiple splittings of the resistive domain generated. The minimum initiation current of this process h...
متن کاملNon-uniform distribution of normal zone in composite superconductors with contact resistance
A region of resistive domains is found in composite superconductors with thermal and electrical contact resistance between the normal metal matrix and the superconductor. The V-I characteristic of 3 sample with resistive domains is found. It is shown that the existence of resistive domains leads to the emergence of hysteresis upon decay and recovery of superconductivity in the presence of trans...
متن کاملQuench energies of composite superconductors
The minimum energy of a local heat pulse Qo, initiating normal zone propagation is an important characteristic of the stability of a superconducting composite. There are many papers concerning, both experimentally and theoretically (usually numerically), the value of Qc for composite superconductors (see, e.g., References 1-3 and references therein). In particular, simple analytical formulae fo...
