Joule-heating power dissipation in a type-II superconductor tube.

The theoretical analysis of the Joule-heating power density in a specific hollow cylinder of a NbZr superconductor is presented. It is seen that the power density, which is the primary source of internal heating neglecting localized annihilation heating, can have a very complicated behavior, especially in the circular region. Rough estimates of the relative temperature changes are made, and the locations at which instabilities are more likely to initiate are considered.

Superconducting magnets and devices for space vehicles and experiments

Superconductivity research has been oriented toward those problems that tend to restrict the greater application of superconducting devices in space research and technology. These include magnetic problems of high field magnets, increasing operating temperatures, and development of useful competitive superconducting instruments.
