基于等离子体的正电子源由于其相当独特的特性引起了研究界的极大关注，这些特性包括广泛的能量可调谐和超短持续时间，可以在紧凑和相对便宜的装置中获得。在这里，我们展示了一个详细的数值研究的正电子束特性可获得的专用用户目标区建议为欧普拉夏设施，第一个等离子体粒子加速器将被建造为一个用户设施的应用。它将表明，在工业和材料科学应用中具有独特性质的MeV级正电子束，以及适用于基础科学和加速器物理的GeV级正电子束，都可以被生产出来。
Plasma-based positron sources are attracting significant attention from the research community, thanks to their rather unique characteristics, which include broad energy tuneability and ultra-short duration, obtainable in a compact and relatively inexpensive setup. Here, we show a detailed numerical study of the positron beam characteristics obtainable at the dedicated user target areas proposed for the EuPRAXIA facility, the first plasma-based particle accelerator to be built as a user facility for applications. It will be shown that MeV-scale positron beams with unique properties for industrial and material science applications can be produced, alongside with GeV-scale positron beams suitable for fundamental science and accelerator physics.
