Abstract

The investigation of proton and heavy ion acceleration was carried out in ultrahigh intensity laser plasma interactions using VULCAN lasers. The first spatially integrated measurement of proton and heavy ion acceleration was performed with nuclear activation techniques. High-intensity laser-plasma interactions provide a unique and potentially important source of nuclear radiation for radioisotope production. By controlling the target conditions and the accelerated ion beam properties, the production of radioisotopes can be controlled effectively.
