Abstract

A method for acceleration of electrons in a smooth cylindrical waveguide in the presence of the magnetic field of a solenoid is proposed. Electrons move in the waveguide along a helical trajectory that is shifted relative to the waveguide axis. Electrons are accelerated at the frequency of the cyclotron resonance along the waveguide axis by wave E01 or E02. It is shown that the acceleration results from synchronous rotation of particles in the transverse cross section of the waveguide and propagation of the wave along the waveguide axis. When the electric field reaches a maximum level and provides acceleration, electrons are located at the center of the waveguide. With a delay of one half of the period, the electric field provides deceleration and electrons are rotated by the magnetic field toward the wall of the waveguide to the region of lower deceleration. Acceleration is the total effect of the electron–field interaction over the period of electron rotation. Parameters of an accelerator are estimated for an energy of 10 MeV.

回旋共振模式下圆波导中E 0n波对电子的加速

摘要

提出了一种在螺线管磁场作用下在光滑的圆柱形波导中加速电子的方法。电子沿着相对于波导轴移动的螺旋形轨迹在波导中移动。电子通过波E 01E 02在回旋共振频率处沿着波导轴加速。结果表明,加速度是由于粒子在波导横截面中的同步旋转以及波沿波导轴的传播而产生的。当电场达到最大水平并提供加速度时,电子位于波导的中心。在周期的一半的延迟下,电场提供了减速,并且电子通过磁场朝着波导的壁旋转到较低减速的区域。加速度是电子旋转期间电子与场相互作用的总作用。估计加速器的参数为10 MeV的能量。
