摘要： A radiation detection, localization, and identification system uses a searching algorithm to identify hypothetical solutions to Compton scatter data. Model based representations of the physical data collection yield the identity and location of radiation sources when correct associations of gamma ray energies and locations are made with detected data events. The system's detector is an array of radiation detectors networked to act as a single detection system. This network has wide area of view and high sensitivity to radiation sources since no collimation is required.

摘要： A probe for determining direction to a radiation source emitting gamma rays with radiation detectors arranged around a scattering element. Incoming gamma rays are deflected by Compton scattering within the scattering element. Scattered radiation is detected in the radiation detectors. The detected pattern of secondary scatter into the detectors is dependent on the location of the source. The analog outputs from the processing electronics are routed from the detectors to a digital processing unit. A directional filter algorithm that combines rates at different detectors decodes the direction to the source.

摘要： A neutron source illuminates suspect material leading to emission of gamma rays characteristic of the isotopes present. The system measures Compton scattering of emitted gamma rays using detectors with three dimension event localization capability. Detection does not require full energy deposition. A spatial correlation of projection vectors is computed by a reconstruction that searches for solutions that generate spatial correlation. Identification and location for contraband material is determined from solutions that generate spatial correlation.

摘要： An ionization detector having a grid of electrodes disposed perpendicular to an oscillating voltage. Charge released from an ionization event oscillates in the detector medium at the same frequency as the applied oscillating voltage. The electrode grid is configured to measure induced oscillating charge from the oscillating ionization charge in the detector. The detector signal is obtained from readout of the induced oscillating charge on the electrodes. Signal processing electronics processes the measured signal from the oscillating induced charge to derive energy and position information of the ionization event. A bias voltage is applied across the detector to further sweep the ionization charge from the active detection volume.
