GROUND-COIL ELECTROMAGNETIC EXCITATION TEST APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a ground-coil electromagnetic excitation test apparatus wherewith a test for generating an electromagnetic force in a ground coil can be conducted just like in actual running without influencing a superconducting magnet. SOLUTION: A ground coil 3 is caused to face an excited superconducting magnet 5; an electric current is caused to pass through the coil 3; and the coil 3 is covered with an aluminum screening plate 4. Thus, a durability verification test of the coil 3 is conducted by generating an electromagnetic force in the conductor part of the coil 3 without influencing the superconducting magnet 5.
