Preparation of superconducting coil through composite
Abstract
The usefulness and application of a superconductor are critically dependent on its critical temperature and on how much current it can carry at how high a field. Nb3Al is potentially very attractive as a practical superconductor because it has the highest critical temperature (in bulk) and critical field. The problem of instability can be alleviated in four ways: utilize a superconductor with sufficiently high critical temperature, bleed off the heat generated, retard the motion of magnetic flux, and make the superconductor so finely divided that heat pulse cannot be generated to get the instability going in the first place. Taking these possible solutions into account, a multistep technique is proposed for forming a superconducting composite coil based on Nb3Al. The inherent advantages of this technique are summarized. The technique includes all the possible solutions in one sweep to remedy the instability encountered in the application of superconductivity to motor and generator devices.
