论文摘要
我们分析了在各向异性非gyrotropic培养基中带有渗透率张量的等离子体成分的电荷在真空通道中移动的电荷的辐射。获得并分析了现场成分的表达式。结果表明该场既包含辐射场和等离子体振荡。大多数注意集中在单位路径长度的电荷的能量损失上。研究了损失对电荷速度和血浆频率的依赖性。考虑辐射损失和极化的相对作用。最有趣的结果是，当介电常数张量的组件之一等于1时，能量损失可以忽略不计，并且电荷速度趋于真空中的光速。这种效果可以有望应用于超级束的准直仪。
We analyze radiation of a charge moving in a vacuum channel in an anisotropic non-gyrotropic medium with plasma-like components of the permittivity tensor. The expressions for field components are obtained and analyzed. It is shown that the field contains both the radiation field and the plasma oscillations. Most attention is focused on the energy loss of the charge per the unit path length. The dependencies of the loss on the charge velocity and the plasma frequencies are studied. The relative roles of radiation loss and polarization one are considered. The most interesting result is that the energy loss is negligible when one of the permittivity tensor components is equal to 1, and the charge velocity tends to the speed of light in vacuum. This effect can be promising for applying in collimators of ultrarelativistic bunches.
