摘要:

在本文中,我们报告的模拟结果,在EuPRAXIA \cite{Walk2017}和EuPRAXIA@ ENUB\_LAB \cite{Ferr2017}项目的框架内,旨在提供一个高亮度的电子束驱动的自由电子激光(FEL),采用等离子体后加速方案。升压等离子体波由数十个\SI{}{\tera\watt}类激光器驱动,并将外部注入光束的能量加倍,达到\GeV{1}。模拟注入的聚束从一个光注入器开始,匹配等离子体,升压,最后匹配到波荡器,在那里它的能力,以产生$O(\num{e11})$光子每次拍摄在\nm{2.7}的自由电子激光辐射验证。

英文摘要:

In this paper, we report results of simulations, in the framework of both EuPRAXIA \cite{Walk2017} and EuPRAXIA@SPARC\_LAB \cite{Ferr2017} projects, aimed at delivering a high brightness electron bunch for driving a Free Electron Laser (FEL) by employing a plasma post acceleration scheme. The boosting plasma wave is driven by a tens of \SI{}{\tera\watt} class laser and doubles the energy of an externally injected beam up to \GeV{1}. The injected bunch is simulated starting from a photoinjector, matched to plasma, boosted and finally matched to an undulator, where its ability to produce FEL radiation is verified to yield $O(\num{e11})$ photons per shot at \nm{2.7}.
