我们描述的方法登记和重建的信封爆炸电子发射电流从一个圆柱形阴极的边缘，它提供了一个皮秒的时间基准的发射电子束与一个亚纳秒的电压前施加到加速间隙。前陡度的变化允许在实验中确定射束起始时间，其中可以使用收集器型电流探针。先进的动态时域反射测量方法提供了准确的数据，电子束电流上升和跟踪变化的阴极发射从脉冲到脉冲的精度小于10 ps。
We describe the methods of registration and reconstruction of an envelope of explosive electron emission current from the edge of a cylindrical cathode, which provides a picosecond time reference of the emitted electron beam with a subnanosecond voltage front applied to the accelerating gap. Variation of the front steepness allows one to determine the beam onset time in the experiments, where a collector-type current probe can be used. The advanced method of dynamic time domain reflectometry provides exact data on electron beam current rise and track changes in the cathode emission from pulse to pulse with a precision of less than 10 ps.
