Abstract
In one aspect, a radiation detector is disclosed, which includes a substrate having a plurality of microcapillary channels, and a crystalline scintillator material disposed in said channels so as to generate a plurality of independent radiation sensing elements associated with each channel for detecting incident radiation and generating an optical radiation in response to the detection of the incident radiation. In some embodiments, the incident radiation can include any of alpha (α), beta (β), gamma (γ), X-ray and neutrons.
Claims27
A radiation detector, comprising:
- a plurality of microcapillary structures,
- wherein said microcapillary structures are at least partially filled with a radiation detecting material so as to provide a plurality of independent radiation sensing elements such that each of the radiation sensing elements is associated with one of said microcapillary structures for detecting incident radiation and generating one or more signals in response to the detection of the incident radiation, wherein the radiation detection material is initially dispersed into the microcapillary structures and then processed inside the microcapillary structures to form within the microcapillary structures the radiation sensing elements having a single crystalline structure or a polycrystalline structure, and wherein said radiation detecting material comprises a semiconductor material, wherein the semiconductor material is configured to generate electric charges in response to detection of the incident radiation, and wherein said radiation detecting material does not comprise a scintillator material.
A radiation detector, comprising:
- a plurality of microcapillary structures formed in a substrate,
- wherein said microcapillary structures are at least partially filled with a radiation detecting material so as to provide a plurality of independent radiation sensing elements such that each of the radiation sensing elements is associated with one of said microcapillary structures for detecting incident radiation and generating one or more signals in response to the detection of the incident radiation, wherein the radiation detection material is initially dispersed into the microcapillary structures and then processed inside the microcapillary structures to form the radiation sensing elements having a single crystalline structure or a polycrystalline structure,
- wherein said radiation detecting material comprises a first scintillator material configured to generate scintillation radiation in response to detection of the incident radiation, and
- wherein said substrate comprises a material exhibiting an index of refraction greater than an index of refraction of said first scintillator material at a frequency associated with the optical radiation such that the optical radiation generated in each of said sensing elements is substantially trapped within that sensing element via internal reflection at interfaces between said first scintillator material and said substrate material.
