An x-ray imaging system includes at least one detector and an x-ray source including an x-ray transmissive vacuum window. The x-ray source is configured to produce diverging x-rays emerging from the vacuum window and propagating along an x-ray propagation axis extending through a region of interest of an object to the at least one detector. The diverging x-rays have propagation paths within an angular divergence angle greater than 1 degree centered on the x-ray propagation axis. The system further includes at least one first motion stage configured to rotate the object about a rotation axis. The system further includes at least one second motion stage configured to move the x-ray source and the at least one detector relative to the object to switch between a laminography configuration and a tomography configuration.

High throughput 3D x-ray imaging system using a transmission x-ray source

A three-dimensional x-ray imaging system includes at least one detector and an x-ray source including an x-ray transmissive vacuum window. The x-ray source is configured to produce diverging x-rays emerging from the vacuum window and propagating along an x-ray propagation axis extending through a region of interest of an object to the at least one detector. The diverging x-rays have propagation paths within an angular divergence angle greater than 1 degree centered on the x-ray propagation axis. The system further includes at least one sample motion stage configured to rotate the object about a rotation axis. The system further includes a sample mount configured to hold the object and comprises a first portion in the propagation paths of at least some of the diverging x-rays and having an x-ray transmission greater than 30% for x-rays having energies greater than 50% of a maximum x-ray energy of an x-ray spectrum of the diverging x-rays.

A marine barrier system comprising first and second barrier sections and a coupler system. The first and second barrier sections comprise first and second main flotation members, respectively, and each main flotation member contains buoyant material. The coupler system is arranged at the juncture of the first and second barrier sections. The coupler system is arranged such that the first and second main flotation members may be placed in a storage configuration and in a deployed configuration. In the storage configuration, the first and second main flotation members are arranged in a parallel, side by side arrangement. In the deployed configuration, the first and second main flotation members are arranged end to end to define a barrier line in a body of water across which movement is limited.
