研究了灯丝直接处在均匀场内的电子(钅仓),在不同的栅极形状下测定了它的聚焦性能,最后确定一种在结构上比较简单、制造容易、安装和调整较为方便的电子(钅仓)。对这种(钅仓)的工作状态和特性进行了分析和测量。 经过运行证明:这种(钅仓)能满足一般电子静电加速器的要求。当加速器的电压为1.3兆伏时,可以供给大于100微安的电子流,在离开电子(钅仓)1.7米的靶上得到电子束直径约为4—5毫米。 Studied the filament directly in the uniform field of electrons (Ying positions), measured in different gate shape of its focusing performance, and finally to determine a structure is relatively simple, easy to manufacture, easy to install and adjust the electronic (钅 warehouse). This kind of work status and characteristics were analyzed and measured. After running proved: This (Ying positions) to meet the general requirements of the electrostatic accelerator. When the accelerator voltage is 1.3 megavolts, an electron flow of more than 100 microamps can be supplied and the electron beam diameter about 4-5 mm on a target 1.7 meters away from the electron (silo).
