Efficient techniques and devices for detecting, locating, tracking, and identifying radiation sources using a network of one or more detectors are disclosed.

Spectral segmentation for optimized sensitivity and computation in advanced radiation detectors

Systems and methods for charged particle detection including statistical reconstruction of object volume scattering density profiles from charged particle tomographic data to determine the probability distribution of charged particle scattering using a statistical multiple scattering model and determine a substantially maximum likelihood estimate of object volume scattering density using expectation maximization (ML/EM) algorithm to reconstruct the object volume scattering density. The presence of and/or type of object occupying the volume of interest can be identified from the reconstructed volume scattering density profile. The charged particle tomographic data can be cosmic ray muon tomographic data from a muon tracker for scanning packages, containers, vehicles or cargo. The method can be implemented using a computer program which is executable on a computer.

Robust statistical reconstruction for charged particle tomography

Techniques, apparatus and systems for obtaining tomographic images of a volume of interest by using charged particle tomography detection systems.

Imaging based on cosmic-ray produced charged particles

Methods and systems for generating bremsstrahlung with enhanced photon flux in a narrow cone at forward angles utilize a thin target of a high-Z material such as gold as radiator, supported on a tube of a low-Z material such as titanium, which tube contains a circulating fluid such as water which acts as a coolant and also may absorb the incident electron beam.

Thin walled tube radiator for bremsstrahlung at high electron beam intensities

Methods, apparatus and systems for detecting charged particles and obtaining tomography of a volume by measuring charged particles including measuring the momentum of a charged particle passing through a charged particle detector. Sets of position sensitive detectors measure scattering of the charged particle. The position sensitive detectors having sufficient mass to cause the charged particle passing through the position sensitive detectors to scatter in the position sensitive detectors. A controller can be adapted and arranged to receive scattering measurements of the charged particle from the charged particle detector, determine at least one trajectory of the charged particle from the measured scattering; and determine at least one momentum measurement of the charged particle from the at least one trajectory. The charged particle can be a cosmic ray-produced charged particle, such as a cosmic ray-produced muon. The position sensitive detectors can be drift cells, such as gas-filled drift tubes.
