A fast modulator for pulse electron gun is briefly described. The maximum output voltage and current are -12kV and 16A respectively. The pulse duration is variable from 50μs to 250μs and both rising and falling time are less than 0.5μs.A maximum output voltage up to -25kV can be expected (in the case of 10A current) provided a photoelectrical coupling element with higher isolation voltage is used.

A P.S. (Power Supply) for multi-filament neutral beam source with an extraction area of 7 x35cm2 is described briefly. It includes Plasma generator P. S. , accelerator P. S. , suppressor P S. and control system. SCR thyristprs of the switch modulator are applied to an arc P. S. which is capable of delivering 1 to 5 kA pulses current at 20 to 150 V and pulse length of 50 ms from a twelve pulse rectifier of the P. S. system to supply energy to the arc chamber load with the duty cycle of 0.1%. Both of switching-no and switching-off time of the circuit are less than 1 ms. The most important feature of the accelerator P.S.is the abolishment of the Parallel fast crowbar switch. In order to increase reliability, two pieces of the FU-104Z type tetrode tube in series were used and each tube can stand the maximum static DC voltage. To improve the fast response of both interrupt and regulation of the overall system, the regulation and switching functions are separated so that they will not interact on each other. The P. S. system is controlled by DBJ-Z80 microcomputer. It has been running reliably under strong electromagnetic field Perturbations.

本文对7×35cm~2多灯丝中性源的供电系统作了简要介绍,包括等离子体发生器、加速极和抑制极的电源和控制系统等。弧电源采用SCR晶闸管调制器,在0.1%的工作比下,从12脉波整流电源向弧室负载传递1~5kA,20~150V,50ms宽的直流脉冲。接通和关断的时间均小于1ms。加速极电源的重要特点是取消了并联快速短路开关。为增加可靠性,使用两只FU-104Z真空四极管串联,每一只均能承受最高直流静态电压。为改善整个系统的遮断和调整的快速响应,将调整和开关两种功能分开,互不影响。电源系统由一台DBJ-Z80微型计算机控制,在强电磁场干扰下能可靠工作。
