小型化中子发生器离子源主要包括放电管、电磁铁、吸极、高频振荡器、氘气输入系统(包括高压储气钢瓶、输气量自动控制调节阀门、输气管等)以及高压电源等,其结构如图1所示。其中放电管采用纯度为99.99%的石英玻璃,底部兰片采用特殊硬铝材料,高频发生器线路图如图2所示,采用了FU-19大功率电子管,它与放电管之间采用电容耦合,离子源底部采用一纵向磁场线圈,以增加电子行程。该小型中子发生器离子源的创新之处在于采用了负高压技术,省去了头部高压电极
Miniaturized neutron generator ion source mainly includes discharge tube, electromagnet, aspirator, high-frequency oscillator, deuterium gas input system (including high pressure gas cylinder, automatic control of gas delivery valve, gas pipe, etc.) and high voltage power supply Etc., the structure shown in Figure 1. One discharge tube with purity of 99.99% of the quartz glass, the bottom of the blue piece of special hard aluminum material, high-frequency generator circuit shown in Figure 2, using FU-19 high-power tube, which discharge tube with a capacitor Coupling, the bottom of the ion source using a longitudinal magnetic field coil to increase the electronic travel. The innovation of this small neutron generator ion source is the use of negative high voltage technology, eliminating the need for head high voltage electrodes
