  • Patent number: 9395454
    Abstract: A device for detecting neutrons includes at least one common module, where a number of solid state sensors are assembled. The sensors are configured in the module side by side and/or stacked in a layered structure. At least one of the sensors includes neutron reactive material as a neutron converter for interacting with neutrons incident thereon to be detected and to release ionizing radiation reaction products responsive to interactions with the incident neutrons. The neutron converters are coupled with corresponding semiconductor elements so that the semiconductor elements interact with the ionizing radiation reaction products for providing electrical charges in proportion to the energy of the ionizing radiation reaction products. The semiconductor elements are configured with electrodes for providing charge collection areas for collecting the electrical charges and to provide electrically readable signals proportional to the collected electrical charges.

  • Patent number: 7605375
    Abstract: A radiation device includes a detector connected to a multi-functional radiation identifying and processing application specific integrated circuit. The detector includes a plurality of individual imaging cells, each imaging cell generating a charge in response to incident radiation events and outputting the generated charge at an imaging cell output. The application specific integrated circuit includes a different circuit connected respectively to a corresponding one of the imaging cell outputs, each circuit receiving and processing the generated charge received from the corresponding one imaging cell output. Each circuit includes a preamplifier for generating a voltage or current amplitude in response to the received charge, a counter, and a mode logic configured for setting the counter to perform, selectively, at least two of a) photon counting, b) analog to digital conversion of the one of the voltage amplitude and the current amplitude, and c) timing measurement of incident radiation events.
