研制了一种基于微型等离子体源的强流等离子体电子发射器。发射等离子体由脉冲高电流气体放电产生。电子发射电流为1 kA，在300 V的脉冲持续时间为10 ms。在本文中描述的原型注入器将用于20 kA的静电电流注入实验中的麦迪逊对称环面反向场箍缩。将复制源以达到该总电流要求。该源具有简单的设计，并已被证明是非常可靠的操作。高发射电流，小尺寸（直径3.7厘米）和低杂质产生使源适合于各种聚变和技术应用。
A high current plasma electron emitter based on a miniature plasma source has been developed. The emitting plasma is created by a pulsed high current gas discharge. The electron emission current is 1 kA at 300 V with a pulse duration of 10 ms. The prototype injector described in this paper will be used for a 20 kA electrostatic current injection experiment in the Madison symmetric torus reversed-field pinch. The source will be replicated in order to attain this total current requirement. The source has a simple design and has proven to be very reliable in operation. A high emission current, small size (3.7 cm in diameter) and low impurity generation make the source suitable for a variety of fusion and technological applications.
