    Abstract: A beam current sensor is composed of a cylindrical super-conductive body having a bridge unit formed on the outer diameter side wherein a beam passes through the inner diameter side. The sensor improves efficiency of creating a magnetic field from a current and can measure a beam current as 1 nA. The bridge unit includes a first coil unit formed so as to have an eddy shape wound counterclockwise from the outer diameter side toward the inner diameter side; a second coil unit formed so as to have an eddy shape wound clockwise from the outer diameter side toward the inner diameter side; and a connection portion for connecting the center position of the inner diameter side of the first coil unit with the center position of the inner diameter side of the second coil.

    Abstract: It is possible to simplify the cooling mechanism of a superconductor, significantly reduce the cost, simplify the measurement work, and reduce the time required for measurement. A beam current meter includes: a cylindrical super conductor beam current sensor arranged in a vacuum vessel in such a manner that the beam incoming into the vacuum vessel is guided to pass through a bore of the vacuum vessel and a bridge portion is formed at the outer diameter, a SQUID arranged at the bridge portion of the beam current sensor; a cylindrical superconductor magnetic shield arranged so as to surround the external diameter side of the beam current sensor in such a manner that the SQUID is positioned between the beam current sensor and the magnetic shield, so that a beam is guided to pass through the bore of the beam current sensor, thereby measuring the beam the beam current of the beam. The beam current meter uses a freezing device as cooling means for cooling the beam current sensor, the SQUID, and the magnetic shield.
