CERENKOV WAKES IN A MAGNETIZED PLASMA FOR HIGH POWER RADIATION GENERATION

这项研究计划的目的是探索一种新的辐射机制的物理学原理，并证明其作为高功率辐射源的可行性。特别地，一个强烈的激光脉冲将被用来激发在直流磁场中传播的激光尾流场。由此产生的尾流场在等离子体/真空边界处与电磁辐射耦合。预计将产生一兆瓦水平的太赫兹辐射，并以持续几百皮秒的脉冲进行探测。

The objectives of this research program are to explore the physics of a new radiation mechanism and to demonstrate its viability as a source of high power radiation. In particular, an intense laser pulse will be used to excite a laser wakefield propagating across a DC magnetic field. The resulting wakefield couples to electromagnetic radiation at the plasma/vacuum boundary. It is anticipated that teraHertz radiation at the level of one megaWatt will be generated and detected in pulses lasting a few hundred picoseconds.
