The cathode rays are always beamed on a fresh area of the anode surface . 阴极射线总是射向阳极表面的新区域。
Chrome blasted structure is good looking and durable with anode surface treatment . with easy - collecting base , lubricators can be applied to work and 给油桶过滤网,能使用过的冲削油过滤回收再使用,
At the delay time when the area on the anode surface bombarded by electrons expands to a maximum field , the upper limit of ion beam current output is reached . the ion beam parameters are an accelerating voltage of 220 kv , an ion current density of 350 a / cm2 with beam pulse width of 70 ns and with composition of 30 % proton and 70 % carbon ions 在电子流对阳极轰击面积达到最大所对应的延迟时间,获得了最大离子束流密度输出,离子束参数为: 220kv , 350a cm ~ 2 , 70ns ,成分约为30 h离子和70 c离子,离子束流密度的波动同样可控制在20 。
