Shielded radiography with a laser-driven MeV-energy X-ray source
We report the results of experimental and numerical-simulation studies of shielded radiography using narrowband MeVenergy X-rays from a compact all-laser-driven inverse-Compton-scattering X-ray light source. This recently developed Xray light source is based on a laser-wakefield accelerator with ultra-high-field gradient (GeV/cm). We demonstrate experimentally high-quality radiographic imaging ...
متن کاملUltrafast Selected Energy X-ray Absorption Spectroscopy (USEXAS) with a Laser-Driven X-ray Source
A laser driven electron x-ray source (LEXS) emitting tungsten Lα lines has been built based on a high repetition rate, terawatt laser system. The Lα characteristic lines overlap with the absorption edge of Ni near 8333 eV. Using this x-ray source, the x-ray absorption spectra near the absorption edge of different Ni compounds have been measured. We term this new method “ultrafast selected energ...
متن کاملX-ray phase-contrast tomography with a compact laser-driven synchrotron source.
Between X-ray tubes and large-scale synchrotron sources, a large gap in performance exists with respect to the monochromaticity and brilliance of the X-ray beam. However, due to their size and cost, large-scale synchrotrons are not available for more routine applications in small and medium-sized academic or industrial laboratories. This gap could be closed by laser-driven compact synchrotron l...
متن کاملMonochromatic computed tomography with a compact laser-driven X-ray source
A laser-driven electron-storage ring can produce nearly monochromatic, tunable X-rays in the keV energy regime by inverse Compton scattering. The small footprint, relative low cost and excellent beam quality provide the prospect for valuable preclinical use in radiography and tomography. The monochromaticity of the beam prevents beam hardening effects that are a serious problem in quantitative ...
متن کاملComparison of Pulsed X-ray Source Digital Radiography with Isotopic Radiography on Pipe
Southwest Research Institute (SwRI ® ) conducted a study to determine whether pulsed x-ray sources used in conjunction with amorphous silicon real-time imaging plates could provide equivalent radiographs to those obtained using isotopic sources with conventional radiographic film for inspection of schedule 40 steel pipe. Radiographic procedures for the two techniques were developed; test welds ...
