Abstract
A method and apparatus for the continuous, contactless testing of a long conductor which consists at least partially of superconductive material in which the conductor is moved, with the superconductive material in the superconducting state, through an external magnetic field which induces shielding currents in the superconductive material, while the magnetic field produced by these shielding currents is measured.
Claims10
A method for the continuous, contactless testing of a long conductor which consists at least partially of superconductive material comprising moving the conductor, with its superconductive material in the superconducting state, through an external magnetic field which induces shielding currents in the superconductor material, and measuring the magnetic field produced by said shielding currents.
Apparatus for the continuous contactless testing of a long conductor consisting at least partially of superconductive material comprising:
- a. a cryostat;
- b. a cylindrical superconducting magnet coil arranged in the cryostat for generating an external magnetic field;
- c. means for introducing the conductor into the magnetic field of the superconducting magnet coil approximately parallel to the coil axis;
- d. means for deflecting the conductor perpendicular to the coil axis and therefore, to the external magnetic field;
- e. means for bringing the conductor out of said coil approximately parallel to the coil axis;
- and
- f. at least one magnetic field probe provided in the vicinity of the deflection points of said means for deflection.
