Abstract
We report experimental results on the status and applications of a novel all-laser-driven hard x-ray source. A single high power (100 TW) laser system accelerate electrons by means of laser wake-field acceleration (0.5 GeV) and generates hard x-rays by means of inverse Compton scattering. The measured x-ray characteristics, narrow-bandwidth (50%) wide tunability range (50 keV to 9 MeV), collimation (5 mrad), compact footprint (university-scale), and femtosecond duration, make this source suitable for applications including high-resolution (< 5 micron) and low-dose x-ray radiography, x-ray diffraction, ultrafast x-ray science, selective nuclear activation analysis, and nonlinear Compton scattering.
