Absolute keV X-ray yield and conversion efficiency in over dense Si petawatt laser plasma
Sergey N. Ryazantsev, Artem S. Martynenko, Maksim V. Sedov +15
Laser-produced plasmas are bright, short sources of X-rays often used for time-resolved imaging and spectroscopy. Absolute measurement requires accurate knowledge of laser-to-x-ray…

Ultrafast Imaging of Laser Driven Shock Waves using Betatron X-rays from a Laser Wakefield Accelerator
J. C. Wood, D. J. Chapman, K. Poder +21
Betatron radiation from laser wakefield accelerators is an ultrashort pulsed source of hard, synchrotron-like x-ray radiation. It emanates from a centimetre scale plasma accelerato…
