高质量相对论性正电子束的产生是实验物理学研究的中心领域，因为它们在从基础科学到实际应用的广泛科学和工程领域具有潜在的相关性。现在，人们越来越有兴趣开发混合机器，将基于等离子体的加速技术与更传统的射频加速器结合起来，以尽量减少这些机器的尺寸和成本。在这里，我们报告了最近使用相对低能量和潜在的桌面激光系统的激光驱动产生高质量正电子束的实验。所获得的结果表明，目前的技术允许在一个紧凑的装置中创建适合注入射频加速器的正电子束。
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. Here we report on recent experiments on laser-driven generation of high-quality positron beams using a relatively low energy and potentially table-top laser system. The results obtained indicate that current technology allows to create, in a compact setup, positron beams suitable for injection in radio-frequency accelerators.
