本文介绍了一种10 kHz脉冲X射线发生器，它采用热阴极整流器和一种新型栅控装置控制X射线的脉宽。储能电容器由电源充电至70 kV，电容器中的电荷由栅极控制装置反复放电至X射线管。栅极电压（负值）、管电压和管电流的最大值分别为-1.5 kV、70 kV和0.4 A。闪光X射线脉冲的持续时间主要由栅极控制装置的时间常数和热电子的截止电压决定。X射线持续时间控制在小于1 ms的范围内;脉冲宽度为0.27 ms，充电电压为70 kV，峰值管电流为0.4 A时，X射线强度为0.92 μC kg− 1（0.5 m/脉冲）。最大重复频率约为10 kHz，焦斑尺寸约为3.5×3.5 mm。
A 10 kHz pulsed X-ray generator utilising a hot-cathode triode in conjunction with a new type of grid control device for controlling X-ray duration is described. The energy-storage condenser was charged up to 70 kV by a power supply, and the electric charges in the condenser were discharged to the X-ray tube repetitively by the grid control device. The maximum values of the grid voltage (negative value), the tube voltage, and the tube current were −1.5 kV, 70 kV, and 0.4 A, respectively. The duration of the flash X-ray pulse was primarily determined by the time constant of the grid control device and the cut-off voltage of thermoelectrons. The X-ray duration was controlled within a region of less than 1 ms; the X-ray intensity with a pulse width of 0.27 ms, a charged voltage of 70 kV, and a peak tube current of 0.4 A was 0.92 μC kg−1at 0.5 m per pulse. The maximum repetition rate was about 10 kHz, and the size of the focal spot was about 3.5×3.5 mm.
