Description
The generation of high-quality relativistic positron beams is a central area of research in experimental physics, due to their applications in a wide range of scientifi
c and engineering areas, ranging from fundamental science to practical applications. There is now growing interest in developing hybrid machines that will combine plasma- based acceleration techniques with more conventional radio-frequency accelerators, in order to minimise the size and cost of these machines. Here we report on recent experiments on laser-driven generation of high-quality positron beams using a relatively low energy, potentially table-top laser system and show how current technology allows to create, in a compact setup, positron beams suitable for injection in conventional accelerators.
