Looking for future high energy accelerators we point at a very strong interaction between relativistic electrons and powerful electromagnetic fields existing in the vicinity of a dielectric cylinder in conditions of resonantly excited whispering gallery modes (WGM). A particular example of the WGM resonance, corresponding to angular index n=22, shows that the accelerating fields are almost 100 times stronger than these in the incident wave. That yields an acceleration rate of about 5 GeV/m with the incident microwave radiation beam of the wavelength lambda=1 cm and a moderately high intensity of P=1 MW/cm2.
展望未来的高能加速器,我们指出在共振激发回音壁模式(WGM)条件下,相对论电子与存在于电介质圆柱体附近的强电磁场之间存在非常强烈的相互作用。对应角指数n = 22的WGM共振的一个具体例子表明,加速场几乎比入射波中的场强100倍。对于波长λ = 1厘米且强度适中较高为P = 1兆瓦/平方厘米的入射微波辐射束,这产生了约5 GeV/m的加速率。
