Abstract
The object of the invention is to provide a biomagnetism measuring device using a high-performance cylindrical shielding apparatus provided with a flange-type plate having an opening formed on a circumferential face, an auxiliary cylinder in which one or plural cylindrical members are connected so that the central axis of the opening of the flange-type plate and each central axis of the cylindrical members are coincident, cylindrical shields having first, second and third angular ranges with the y-axis, a revolving door having a cutout in a portion parallel to the y-axis and acquired by integrating the cylindrical shields, shield bases for supporting the cylindrical shield to which the flange-type plate is connected in a circular-arc part at both ends, revolving parts for revolving the revolving door in a circumferential direction of the y-axis along a circumferential part of the cylindrical shield and opening or closing an opening in the circumferential direction, a cryostat arranged inside the opening of the auxiliary cylinder and the opening and a SQUID fluxmeter arranged on a measurement face parallel to an XY plane inside the cryostat held at low temperature and characterized …
