摘要

通过准线性激光唤醒场电子加速的一维模型，得到了电子束能量扩散对时间和注入持续时间的分析依赖关系，并以电子能量相对于等离子体波相位的相位肖像表示。与标准的气泡式方法相比，通过转移到具有另一种相位轨迹的去加速部分（通过降低等离子体波的振幅）来产生具有可变能量和较低能量分布的电子束的方法已经开发出来。分析得出的结果成功地描述了之前在齐姆巴罗夫等人（2024 arXiv:2403.19828）的实验和数值（PIC）数据中获得的关键特征。

Quasi-monoenergetic electron beam from LWFA: analytical approach

Analytical dependence of the energy spread of electron beam on time and injection duration has been obtained with the 1D model of the quasi-linear laser wakefield electron acceleration, presented as phase portraits of electron energy relative to the plasma wave phase. The method for producing electron beams with variable energy and a lower energy spread compared to a standard bubble-like approach by transferring to a deaccelerating part with another phase trajectory (by reducing the plasma amplitude of a wave) has been developed. The analytically obtained results successfully describe key features of the previously obtained in Tsymbalov et al (2024 arXiv:2403.19828) experimental and numerical (PIC) data.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
