    Abstract: An apparatus for detecting radiation comprises a radiation converter (101), a photodetector (102), and a light guide (103) for conducting photons emitted by the radiation converter. The radiation converter is a layer in contact with a first surface (105) of the light guide and the photodetector is attached to an opposite side of the light guide. A convex second surface (106) of the light guide receives the photons from the radiation converter and has a reflective coating (104) reflecting the photons backwards to the radiation converter that, in turn, reflects the photons to the photodetector. As the photons are reflected back-and-forth in the above-mentioned way, the photons can be directed to a small area even if the light guide is short in a direction (z) perpendicular to the first surface of the light guide.

    Abstract: Boron nitride nanotubes (BNNTs) with 10B combined with a scintillation gas can serve as the basis for detecting thermal neutrons by detecting light from the decay products of the thermal neutron's absorption on the 10B atoms in the BNNT Material as the resultant decay products pass through the scintillating gas. BNNTs with 11B can be utilized as a scaffold for 238U and combined with a scintillation gas as the basis for detecting fast neutrons via detecting light from the fission decay products passing through the scintillating gas. Both technologies provide high spatial and temporal resolution for the detection of thermal neutrons and fast neutrons respectively.

    Abstract: The invention relates to charged-particle segmented strip detectors, in which the strips comprise one or more scintillating fibers and the fibers are arranged in the form of a strip and are folded onto themselves so as to form a loop with a bending radius which is 0 or parallel and spaced in the case where alpha = 0. These detectors may be one-dimensional or two-dimensional position detectors or tracking detectors and may be combined with residual range detectors. The invention also relates to compression of the number of read-out channels of these detectors obtained by means of suitable grouping of the fibers at the two read-out ends thereof, obtaining a compression factor equal to 2·√N, where N = the number of read-out channels of the fibers, in quadruple coincidence. The detectors according to the invention are applicable to apparatus for radiography or tomography using charged particles.

    Abstract: Boron nitride nanotubes (BNNTs) having a second scintillating material, and in some embodiments an enhanced 10B content, may be used for efficient thermal neutron detection. The second scintillating material may be a crystal coating on the nanotubes, and/or crystal dispersed within the BNNT material. Crystal-coated BNNT materials enable detecting thermal neutrons by detecting light from the decay products of the thermal neutron's absorption on the 10B atoms in the BNNT material, as the resultant decay products pass through the crystal-coating. Embodiments of thermal neutron detectors are described. Methods for preparing BNNTs with a second scintillating material are also described.
