摘要：

The comparative efficiency and beam characteristics of high-energy ions generated by high-intensity short-pulse lasers (similar to1-6x10(19) W/cm(2)) from both the front and rear surfaces of thin metal foils have been measured under identical conditions. Using direct beam measurements and nuclear activation techniques, we find that rear-surface acceleration produces higher energy particles with smaller divergence and a higher efficiency than front-surface acceleration. Our observations are well reproduced by realistic particle-in-cell simulations, and we predict optimal criteria for future applications.
