摘要

给出了在真空二极管中产生的持续时间为10–12 ps的失控电子束和持续时间为2 ns的电子束激发的晶体和陶瓷的脉冲阴极发光参数的比较研究结果。结果表明，在这两种情况下，谱带的发光光谱和衰变动力学是一致的。当被失控的电子束激发时，观察到较低的发光强度。在某些情况下，发现发光的出现相对于电子束作用的开始延迟。失控电子束激发时出现延迟的机制与发光上升过程有关。

Specific Features of Pulsed Cathodoluminescence under Excitation by Nanosecond and Subnanosecond Electron Beams

The results of comparative investigations of the parameters of pulsed cathodoluminescence of crystals and ceramics excited by runaway electron beams with a duration of 10–12 ps and by electron beams with a duration of 2 ns generated in a vacuum diode are presented. It is shown that the luminescence spectrum and the decay kinetics of the bands coincide in both cases. When excited by a beam of runaway electrons, a lower luminescence intensity is observed. In certain cases, a delay in the appearance of luminescence relative to the onset of the electron-beam action is found. The mechanism for the appearance of a delay upon excitation by the beam of runaway electrons is associated with the process of luminescence rise.
