摘要

具有相对论强度的激光脉冲在高密度透明等离子体中传播过程中的相对论性自俘获伴随着超硬x射线范围内超亮同步加速器辐射的产生。这项工作提出了具有给定能量的激光脉冲持续时间对该辐射特性的影响的研究。结果表明，目前可用的强力激光脉冲压缩大大提高了转换成同步辐射的效率，并使x射线源的亮度提高了一个数量级。

Generation of Synchrotron Radiation During the Interaction between a Multiterrawatt Laser Pulse and a Transparent Plasma

The relativistic self-trapping of a laser pulse with relativistic intensity during its propagation in a high-density transparent plasma is accompanied by the generation of ultrabright synchrotron (betatron) radiation in the ultrahard X-ray range. This work presents a study of the effect of the duration of the laser pulse with a given energy on the characteristics of this radiation. It is shown that the currently available compression of powerful laser pulses substantially increases the efficiency of conversion into synchrotron radiation and also increases the brightness of the X-ray source by one order of magnitude.

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
