Laser-driven ion acceleration -20 years of research: applications and prospect- — •Markus Roth — Technische Universität Darmstadt, Institut für Kernphysik, Darmstadt, Germany — Focused Energy GmbH, Im Tiefen See 45, Darmstadt, Germany

With the advent of ultra-intense laser beams at the beginning of this century we entered a new regime for ion acceleration. Intensities exceeding 1018 W/cm2 allowed for new acceleration schemes, based on relativistic plasma physics, resulting in intense, directed ion beams of excellent quality. The particle energies of the ion beams currently exceed the range of 100 MeV. Over the last 20 years, research has focused on understanding the underlying physics and optimizing the process. Moreover, new mechanisms have been discovered, sometimes using large-scale computer simulations and tested in the laboratory.

I will present the development of laser-driven ion acceleration over the years and the current state-of-the-art.

Based on the research, applications have been identified to make use of the unique parameters of laser-driven ion beams. They range from medical applications to novel diagnostics capabilities to the production of intense bursts of neutrons for non-destructive testing and to using laser ion beams as an ignitor in fusion energy.

Recently the neutron production and fusion research has gain significant interest, not only from the academia but also from private industry and investors. I will show some of the recent developments and upcoming prospects for non-destructive testing and fusion energy.
