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 ≤100 times the diameter or the side size, in the case of square cross-sections, and the strip is folded so that its end portions form an angle 0≤α≤90° beyond the curvature, said end portions being superimposed in the case where the angle is α ≠ 0 or parallel and spaced in the case where α = 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 translation: 本发明涉及带电粒子分段条带检测器，其中条带包括一个或多个闪烁纤维，并且纤维以带状的形式布置，并且折叠到它们自身上，以形成弯曲半径的环， =直径或侧面尺寸的100倍，在正方形横截面的情况下，并且条被折叠使得其端部形成超过曲率的角度0 <=α<= 90°，所述端部部分叠加在 在α= 0的情况下角度为α<> 0或平行且间隔的情况。这些检测器可以是一维或二维位置检测器或跟踪检测器，并且可以与剩余范围检测器组合。 本发明还涉及通过在其两个读出端适当地分组光纤获得的这些检测器的读出通道的数量的压缩，获得等于2·N的压缩因子，其中N = 纤维的读出通道的数量是四重巧合。 根据本发明的检测器可应用于使用带电粒子的放射照相或断层摄影装置。
