    • An electron injector including an electron source and a conducting grid situated close to the electron source, one or more RF accelerating/bunching cavities operating at the same fundamental RF frequency; a DC voltage source configured to bias the cathode at a small positive voltage with respect to the grid; a first RF drive configured to apply an RF signal between the cathode and grid at the fundamental and third harmonic RF frequencies; and a second RF drive configured to apply an RF drive signal to the accelerating/bunching cavities. Electrons are emitted by the cathode and travel through the grid to the accelerating/bunching cavities for input into an RF linac. The first RF drive applies a first RF drive signal at the fundamental frequency of the linac plus higher harmonics thereof to the gap between the cathode and the grid to cause the emitted electrons to form electron bunches and the second RF drive applies a second RF drive signal to the accelerating/bunching cavities on the other side of the grid to further accelerate and optimize the size of the electron bunches. Because the applied RF signals contain at the fundamental linac frequency, the electrons are bunched at that frequency and each RF bucket of the linac is filled with an electron bunch.
    • 一种电子注入器,包括靠近电子源的电子源和导电栅格,在相同的基本RF频率下工作的一个或多个RF加速/聚束腔; DC电压源,被配置为相对于所述栅极以小的正电压偏压所述阴极; 第一RF驱动器,被配置为在所述基极和三次谐波RF频率处在所述阴极和电网之间施加RF信号; 以及被配置为将RF驱动信号施加到加速/聚束空腔的第二RF驱动器。 电子由阴极发射并通过栅格传播到加速/聚束腔,以输入到RF线性加速器。 第一RF驱动器将线性加速器的基频加上其高次谐波的第一RF驱动信号施加到阴极和栅格之间的间隙,以使发射的电子形成电子束,并且第二RF驱动器施加第二RF驱动信号 到网格另一侧的加速/聚束腔,以进一步加速和优化电子束的尺寸。 因为所施加的RF信号包含基线频率,所以电子以该频率聚束,并且直线加速器的每个RF桶被电子束填充。
