Abstract
A gamma ray detector is disclosed. A scintillation layer (60), for example of barium fluoride, is formed of a plurality of adjacent elongate rods, each rod being elongate within the plane of the layer, and being provided with a plurality of slots (62) distributed along the length of the rod and extending in a width direction also coplanar with the layer. Behind the scintillation layer a sensor determines a position of uv photons exiting the layer.
Claims20
A gamma ray detector comprising:
- a scintillation layer, having opposing first and second sides, for converting a gamma ray photon received at the first side into a plurality of ultraviolet photons at least some of which are received at and exit through the second side;
- and
- a sensor adapted to determine a position of the exiting photons,
- wherein the scintillation layer comprises a plurality of adjacent elongate rods formed of a scintillation material, each rod being elongate along a length coplanar with the layer, having a width also coplanar with the layer, and having a depth through the layer, and each rod is provided with a plurality of slots distributed along the length of the rod and extending in the width direction.
