Considerations for the Design of a Multi-Color High-Speed X-Ray Computed Tomography Diagnostic.

摘要

This report describes the development and work progress of designing and building an improved radiographic computed tomographic technique that has the potential to provide material specificity of a three-dimensional spatial field, relatively quickly in time on the order of <100 ns, with mm3 voxel resolution (a voxel is the three-dimensional equivalent of a pixel). This report details thoughts and work performed focusing on potential issues regarding: the robustness of a structural frame and components of the diagnostic; how to obtain accurate measurements of the x-ray flux verses energy output of the multiple x-ray sources, which is necessary to obtain material specificity; electrical grounding and shielding of the numerous pulse power sources; and collection of static data that can be used to prove the premise of material specificity in a nondynamic state. Conclusions are made suggesting possible paths forward for construction of a device that would have the potential to make measurements of dynamic events with high-impulse loadings.
