    Abstract: A neutron detector with a unique neutron detecting element is disclosed. The neutron detecting element has an inner cylindrical neutron scintillator where a neutron detection body including a ZnS phosphor, and a neutron converter material which contains 6Li or 10B is arranged outside of the cylindrical substrate; a scintillator fluorescence detection body made by placing coiled wavelength shift fibers where two wavelength shift fibers are wound in parallel along the cylindrical substrate on said inner cylindrical neutron scintillator; and an outer cylindrical neutron scintillator where a neutron detection body is arranged inside of the cylindrical substrate, the outer cylindrical neutron scintillator being arranged on the scintillator fluorescence detection body. The fluorescence signals converted into pulse signals by two optical detectors are led to a coincidence circuit, and when two fluorescence signals are measured simultaneously during the predetermined period of time, a neutron signal is output.

  • Patent number: 9263227
    Abstract: An X-ray tube includes a radiopaque substrate including a window portion, an X-ray transmission window closing the window portion, an X-ray target provided at the window portion from an inner surface side of the substrate, a highly-evacuated container portion attached to the inner surface of the substrate, a cathode, a first control electrode and a second control electrode provided inside the container portion. A shielding electrode is provided at the inner surface of the substrate so as to surround the window portion. Electrons collide with the X-ray target to generate X-rays. Electrons reflected on the X-ray target between the shielding electrodes are absorbed by the shielding electrodes, so an inner surface of the container portion is not charged. The electron emission from the cathode is not affected by the reflected electrons, so a change in target current is small, and thus X-rays of substantially constant intensity can be radiated.

  • Publication number: 20150382440
    Abstract: In an X-ray radiation source, a counter wall made of alkali-containing glass, out of walls of a housing of an X-ray tube, is arranged opposite to a high-voltage region VH of a power supply unit including a high-voltage generation module which generates a negative high voltage to be applied to a filament. This configuration prevents an electric field from being generated in the counter wall and thus suppresses precipitation of alkali ions from the glass. Therefore, it prevents change in potential relationship between electrodes at different potentials such as the filament, grid, and target and prevents occurrence of a trouble of failure in maintaining a desired X-ray amount, thus enabling stable operation to be maintained.

    Abstract: In an X-ray radiation source, a counter wall made of alkali-containing glass, out of walls of a housing of an X-ray tube, is sandwiched between a filament and an electric field control electrode to each of which a negative high voltage is applied. This configuration prevents an electric field from being generated in the counter wall and thus suppresses precipitation of alkali ions from the glass. Therefore, it prevents change in potential relationship between electrodes at different potentials such as the filament, grid, and target and enables stable operation to be maintained, without occurrence of a trouble of failure in maintaining a desired X-ray amount.
