摘要

我们建议使用具有引导轴向磁场的波动器作为“踢子”，形成一群轴向速度分布较小的电子陀螺振荡器。束束的回旋辐射导致电子旋转的振荡速度丧失，但不影响电子的轴向速度。利用这一效应，可以将波动段中电子轴向速度扩散的最小化转化为回旋辐射段中电子能量扩散的最小化。

Cyclotron radiation cooling of a short electron bunch kicked in an undulator with guiding magnetic field

We propose to use of an undulator with the guiding axial magnetic field as a ``kicker'' forming a bunch of electron gyro-oscillators with a small spread in the axial velocity. The cyclotron emission from the bunch leads to losing oscillatory velocity of electron gyrorotation, but it does not perturb the axial electron velocity. This effect can be used for transformation of minimization of the spread in electron axial velocity in the undulator section into minimization of the spread in electron energy in the cyclotron radiation section.

期刊介绍： Physical Review Special Topics - Accelerators and Beams (PRST-AB), is a peer reviewed, purely electronic journal, distributed without charge to readers and funded by contributions from national laboratories. It covers the full range of accelerator science and technology: subsystem and component technologies, beam dynamics; accelerator applications; and design, operation, and improvement of accelerators used in science and industry. This includes accelerators for high-energy and nuclear physics, synchrotron radiation production, spallation neutron sources, medical therapy, and intense beam applications.
