本文简要描述了供脉冲电子枪用的快速调制器。当最高工作电压为负12kV时,能提供最大电流为16A、宽度为50—250μs、上升和下降时间均小于0.5μs的脉冲电流。如用耐压更高的光电耦合器件,当脉冲电流为10A时,工作电压可望达到20—25kV。
This article briefly describes a fast modulator for pulse electron guns. When the maximum operating voltage is negative 12kV, can provide a maximum current of 16A, the width of 50-250μs, rise and fall times are less than 0.5μs pulse current. Such as the use of higher voltage opto-coupler, when the pulse current is 10A, the operating voltage is expected to reach 20-25kV.
