Precision x-ray spectroscopy of intense laser-plasma interaction experiments — •Nigel Woolsey — Department of Physics, University of York, York, YO10 5DD, United Kingdom
Detailed knowledge of electric and magnetic fields and properties of fast electron beams following the interaction of high-intensity, ultra-short laser pulses is a key area for fast ignition and secondary source generation. X-ray spectroscopy is a powerful method for in situ measurement of the physics that occurs in laser-produced plasmas. Combining high spectral and spatial resolution enables measurement of plasma waves, magnetic fields and the properties of electron beams as they propagate through a target. This discussion will include experiments demonstrating the viability of precision spectroscopy at laser intensities of 1021 Wcm-2, a significant milestone as this suggests that spectroscopy is as an effective probe of fast electron physics in regimes relevant to a new generation of lasers such as ELI and HiPER.
