    摘要: A borehole muon detector comprises a sensor housed in a housing, the sensor including: a plurality of photodetector elements; at least one printed circuit board in electrical communication with the plurality of photodetectors and including an integrated electronic circuit for tracking time; a first helical bundle of scintillator fibers; and an oppositely wound helical bundle of scintillator fibers. Each scintillator fiber of each bundle is optically connected to a photodetector. The sensor comprises a plurality of scintillator bars, each comprising an optical fiber extending from a first end to a second end, and vertically disposed in the bore defined by the helical bundles of fibers. Each optical fiber of each scintillator bar is optically connected to a photodetector element.

    摘要: A particle beam microscope comprises: a particle beam source for generating a particle beam; an objective lens for focusing the particle beam in an object plane; a first scintillator for converting electrons into light; a second scintillator for generating light by way of electrons; and light detectors for detecting the generated light. The distance of second scintillator from the object plane is greater than the distance of the first scintillator from the object plane. The second scintillator has a surface which faces the object plane and through which electrons arriving from the object plane pass. The electrons are converted into light by the second scintillator. The light generated by the first scintillator and detected by a light detector is incident on the second scintillator.
