摘要
在某些电子束焊机中,可以通过调节栅偏电压的大小来控制电子束束斑的直径。在加栅偏电压和不加栅偏电压的两种情况下,进行下束实验,验证栅偏电压对电子束束斑形状和尺寸的影响。
In some electron beam welding machines,the diameter of the beam spot can be controlled by adjusting the size of the gate bias voltage. In this experiment,the effect of the gate bias voltage on the shape and size of the beam spot is verified in the two cases with the increase of the gate voltage and the bias voltage.
