摘要： A semiconductor material for radiation absorption and detection comprising a composition of stoichiometry Li(M12+, M22+, M32+, . . . )(G1V, G2V, G3V, . . . ) and exhibiting an antifluorite-type order, where Li=1, (M12++M22++M32++ . . . )=1, and (G1V+G2V+G3V+ . . . )=1. The material provides two useful characteristics: [1] a high Li-site density, which when enriched in 6Li, produces exceptional neutron-absorbing capabilities and [2] a semiconducting band-gap for the efficient conversion of absorbed photon and neutron energies into electrical currents. These characteristics can be exploited in applications for power generation or the spectroscopic detection of gamma and neutron radiation. The material can be tailored so as to detect only gamma photons, detect only neutron particles, or simultaneously detect gamma photons and neutron particles.

摘要： An integrated radiation detector having a pulse-mode operating photosensor optically coupled to a gamma sensing element and a neutron sensing element is disclosed. The detector includes pulse shape and processing electronics package that uses an analog to digital converter (ADC) and a charge to digital converter (QDC) to determine scintillation decay times and classify radiation interactions by radiation type. The pulse shape and processing electronics package determines a maximum gamma energy from the spectrum associated with gamma rays detected by the gamma sensing element to adaptively select a gamma threshold for the neutron sensing element. A light pulse attributed to the neutron sensing element is a valid neutron event when the amplitude of the light pulse is above the gamma threshold.

摘要： An array of position-sensitive avalanche photodiodes is provided in which output signal contacts from corners of each photodiode are grouped in common for readout. Each photodiode may be provided on a single wafer or chip, with photodiodes being separated by a trench or a groove. Corners of each photodiode include contacts for reading out signals resulting from gamma rays incident events in an adjacent scintillator. Grouping of the contacts into common output channels reduces the number of output channels, while still permitting localization of gamma ray incident events in the scintillator crystals. The photodiode array may be positioned adjacent to one face of a scintillator, with a photomultiplier tube to be positioned adjacent to another. The detector arrangement may be used for positron emission tomography imaging and similar techniques.
