Towards hard X-ray imaging at GHz frame rate
hard X-ray imaging GHz frame rate Instrumentation and Detectors Plasma Physics
2012/5/17
Gigahertz (GHz) imaging using hard X-rays ($\gtrsim$ 10 keV) can be useful to high-temperature plasma experiments, as well as research using coherent photons from synchrotron radiation and X-ray free ...
Single shot phase contrast imaging using laser-produced Betatron x-ray beams
Betatron x-ray beams
2011/9/5
Development of x-ray phase contrast imaging applications with a laboratory scale source have been limited by the long exposure time needed to obtain one image. We demonstrate, using the Betatron x-ray...
Comparison of hard x-ray production from various targets in air using a short pulse kHz laser with photon production from a high power multifilament laser beam from the same targets in air
multifilament short pulse kHz laser
2011/9/5
Over the last few years there has been much interest in the production of hard X-rays from various targets using a kHz short pulse laser at intensities above 1014Wcm-2 (A). Most of these studies have ...
Controlled Betatron X-ray radiation from tunable optically injected electrons
Betatron X-ray radiation tunable optically injected electrons
2011/9/5
The features of Betatron X-ray emission produced in a laser-plasma accelerator are closely linked to the properties of the relativistic electrons which are at the origin of the radiation. While in int...
Plasma Focus as a Powerful Hard X-Ray Source for Ultrafast Imaging of Moving Metallic Objects
Plasma Focus a Powerful Hard X-Ray Source Ultrafast Imaging Moving Metallic Objects
2010/10/27
Using high energy, pulsed X-rays, generated by a 4.7 kJ Plasma Focus operated with deuterium - argon admixtures, images of fast rotating metallic pieces were obtained. This illustrates the potential a...
