A particle beam detector is disclosed. The particle beam detector can include a particle beam receiving portion configured to convert particle beam energy to heat, and a plurality of temperature measuring devices disposed about the particle beam receiving portion. A location of a particle beam on the particle beam receiving portion can be determined by a temperature difference between at least two of the plurality of temperature measuring devices.

Particle beam detector

Methods and apparatus to capture images of fluorescence generated by ionizing radiation and determine a position of a beam of ionizing radiation generating the fluorescence from the captured images. In one embodiment, the fluorescence is the result of ionization and recombination of nitrogen in air.

Method and apparatus to monitor a beam of ionizing radiation

Methods and apparatus for a detector system to detect gamma and neutron radiation. In one embodiment, a detector comprises a tank to hold a liquid, a plurality of tubes adjacent the tank to detect neutrons, and a plurality of photon detectors to detect Cherenkov light generated by gamma radiation in the liquid. The tank is configured to contain the liquid so that the liquid generates the Cherenkov light and moderates the neutrons.

Methods and apparatus for integrated neutron/gamma detector

Methods and apparatus for a radiation monitor. In one embodiment, a radiator monitor comprises a housing, a detector material having an adjustable density in the housing, an optical coupler adjacent the detector material to receive Cherenkov energy generated in the detector material, a photodetector coupled to the optical coupler, and a processing module coupled to the photodetector to determine whether a detection threshold is exceeded.

Methods and apparatus for a radiation monitor

The present disclosure relates, according to some embodiments, to apparatus, devices, systems, and/or methods for real-time detection of a concealed or camouflaged explosive device (e.g., EFPs and IEDs) from a safe stand-off distance. Apparatus, system and/or methods of the disclosure may also be operable to identify and/or spatially locate and/or detect an explosive device. An apparatus or system may comprise an x-ray generator that generates high-energy x-rays and/or electrons operable to contact and activate a metal comprised in an explosive device from a stand-off distance; and a detector operable to detect activation of the metal. Identifying an explosive device may comprise detecting characteristic radiation signatures emitted by metals specific to an EFP, an IED or a landmine. Apparatus and systems of the disclosure may be mounted on vehicles and methods of the disclosure may be performed while moving in the vehicle and from a safe stand-off distance.

Apparatus and methods for real-time detection of explosives devices

According to one embodiment, a system for interrogating hidden contents of a container comprises a controller, a detector system, and a data system. The controller receives a selection of a source mode of source radiation to generate to interrogate contents of a container. The source mode selection comprises a neutron mode, a gamma ray mode, or a combined neutron-gamma ray mode. The controller instructs a cyclotron to generate the source radiation according to the source mode selection. The detector system detects radiation emitted from the contents in response to the source radiation. The data system analyzes the emitted radiation and describes the contents according to the analysis.
