Method for producing superconducting coil.

摘要

in a superconductive coil having no bobbin in its inside, there is provided a method for producing a superconducting coil (1) having a good cooling ability. The method is characterized in that the superconducting coil (1) is formed around a bobbin (5), a support cylinder (2) is fitted around the outer periphery of the bobbin and thereafter, the bobbin is removed apart from the coil. A desired prestress may be applied from the support cylinder to the outer periphery of the coil. Therefore, it is possible to improve a thermal conductance and prevent the coil from moving during the superconducting operation.
