Description

The generation of high-quality relativistic positron beams is a central area of research in experimental physics due to their potential relevance in a wide range of scientific 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. Moreover, the physics of electron-positron plasmas is attracting renewed interest, due to the presence of this exotic state of matter in a wide range of extreme astrophysical scenarios. Here we report on recent results obtained by our group in the generation of high-quality positron beams and neutral electron-positron beams [1-5]. After comparing our experimental results with alternative methods proposed in the literature, we will discuss the main physical principles at play and finally propose future experimental directions in this area.
