Definitions

  • Figure 14c is a perspective view of a masked detector configuration based on a piece of scintillation material with a trapezoidal cross section
  • Figure 15 is a perspective view showing construction details of a bar- shaped, masked detector module similar to Figure 14a, but with photo- detectors placed along its rear face;
  • multiple optical fibers may be used to route the light to multichannel detectors.
  • the pieces of scintillation material that form the core of a scintillation based detector are clad in a radiolucent, light reflecting material such as aluminum. This increases the brightness of the pulse of light as perceived by the light detectors. However, in some situations, this reflectivity may interfere with the ability of the light detectors to determine the longitudinal position where the photon struck the scintillation material.
