Abstract
In this paper, we report on measurements of bremsstrahlung in laser ion acceleration experiments from ultra-thin, polymer-based target foils. The influence of laser polarization on the generated \(\gamma\) radiation, the maximum achievable proton energy and the total proton number is investigated. A clear benefit in terms of \(\gamma\) radiation reduction by the use of circular polarized light can be observed. At the same time, the total number of accelerated protons was increased.
