Increased flux of high energy particles and X-rays from relativistic nanostructured plasmas

The acceleration of charged particles (electrons and ions) and generation of hard X-rays from femtosecond high contrast laser-driven relativistic plasma using nanostructured bulk targets was studied. It was shown that the flux of charged particles may be significantly enhanced at interaction with nanomodified surfaces. The effect of nanostructures shape and size onto the particles energy and angular distribution was studied. Manifold increased hard X-ray flux was detected for high-Z structured targets opening the opportunity for fast X-ray imaging.
