Zusammenfassung: | To provide an inspection apparatus capable of inspecting soundness of superconducting state of a cylindrical superconductor.SOLUTION: The inspection apparatus comprises: a shield magnetic field detection sensor disposed facing a cylindrical circumferential surface of a superconducting cylindrical superconductor 7; an axis direction mobile unit moving the shield magnetic field detection sensor in an axis direction of the cylindrical superconductor; a rotation unit rotating the shield magnetic field detection sensor about a central axis of the cylindrical superconductor; and a magnet disposed in a position where its N-pole faces the cylindrical circumferential surface of the cylindrical superconductor across the shield magnetic field detection sensor, and movable along with the shield magnetic field detection sensor. The shield magnetic field detection sensor detects a shield magnetic field formed by shielding a magnetic field applied to the cylindrical superconductor from the magnet while moving along the cylindrical circumferential surface of the cylindrical superconductor by driving of the axis direction mobile unit and the rotation unit. This allows inspection of soundness of the superconducting state of the cylindrical superconductor in the cylindrical circumferential surface.SELECTED DRAWING: Figure 8
【課題】 円筒状超電導体の超電導状態の健全性を検査することができる検査装置を提供すること。【解決手段】 検査装置は、超電導状態の円筒状超電導体7の円筒周面に対面配置した遮蔽磁場検出センサと、遮蔽磁場検出センサを円筒状超電導体の軸方向に移動させる軸方向移動ユニットと、遮蔽磁場検出センサを円筒状超電導体の中心軸回りに回転させる回転ユニットと、N極が遮蔽磁場検出センサを挟んで円筒状超電導体の円筒周面に対面する位置に配設され、遮蔽磁場検出センサとともに移動可能な磁石と、を備える。遮蔽磁場検出センサは、磁石から円筒状超電導体に印加される磁場が遮蔽されることにより形成される遮蔽磁場を、軸方向移動ユニット及び回転ユニットの駆動によって円筒状超電導体の円筒周面に沿って移動しながら検出する。これにより、円筒状超電導体の円筒周面内における超電導状態の健全性が検査される。【選択図】 図8 |
