    Abstract: Provided is an image type electron spin polarimeter. It at least comprises a scattering target, a two-dimensional electron detector and an electron bending unit, wherein the electron bending unit is used for bending the orbit of the incident (scattered) electrons to a first (second) angle to arrive the scattering target (two-dimensional electron detector) with an optimal incident angle, and to transfer the image of the electron intensities from the entrance plane (scattering target) to the scattering target (two-dimensional electron detector) with small aberrations, and to separate the orbits of incident and scattered electrons to increase the degree of freedom of the geometric configuration of each component of the spin polarimeter. At least one of the first and second angles is not 0°, thereby achieving the first transfer of the two-dimensional image of electron intensities on the entrance plane to the scattering target and the second transfer from scattering target to the two-dimensional electron detector respectively with small aberrations, and then achieving multichannel measurements of the electron spin.

    Abstract: A method is proposed herein to detect high atomic number materials, such as Special Nuclear Materials, within a container based on muon tomography. The container is modeled as a plurality of volume elements. Information related to an initial trajectory and a final trajectory of each muon passing through the container is received. Additionally, a set of initial outer prong vectors and a set of final outer prong vectors are created. Then, a plurality of vector combinations are created from a selected initial vector and a selected final vector. A metric is determined and associated with each vector combination. A subset of the plurality of vector combinations is associated with each volume element and an estimated scattering density is determined and assigned to the volume element. Based on the estimated scattering density assigned to the volume elements, a three dimensional image of the container may be generated.

    Abstract: Mineral definitions each include a list of elements, each of the elements having a corresponding standard spectrum. To determine the composition of an unknown mineral sample, the acquired spectrum of the sample is sequentially decomposed into the standard spectra of the elements from the element list of each of the mineral definitions, and a similarity metric computed for each mineral definition. The unknown mineral is identified as the mineral having the best similarity metric.
