Abstract

An injector of a beam of fast deuterium atoms with an energy of 55 keV, a power of 1 MW and a pulse duration of up to 2 s has been developed in order to further increase the plasma heating power at the TCV tokamak (Tokamak à Configuration Variable, Lausanne, Switzerland). The ion beam is formed in the injector by a triode multislit ion-optical system with slit-shaped holes. The electrodes are spherical segments, which provide ballistic focusing of the beam at a distance of 4.0 m. The selection of ions for the formation of a primary ion beam is carried out from the surface of the plasma emitter, which is created and maintained in the discharge chamber of the plasma source using a high-frequency induction discharge. The design of the injector is presented, and its main elements, power supply, and control systems are described in detail. The results of its experimental tests at the TCV tokamak are presented.

用于等离子体加热的聚焦氘原子束注入器

为了进一步提高TCV托卡马克（托卡马克配置变量，洛桑，瑞士）的等离子体加热功率，已经开发了一种能量为55kev，功率为1mw，脉冲持续时间长达2s的快氘原子束注入器。离子束在注入器中由带有狭缝状孔的三极管多缝离子光学系统形成。电极是球形段，在4.0米的距离上提供光束的弹道聚焦。用于形成初级离子束的离子的选择是从等离子体发射器的表面进行的，等离子体发射器使用高频感应放电在等离子体源的放电室中产生并保持。介绍了喷油器的设计，详细介绍了其主要元件、电源和控制系统。本文介绍了其在TCV托卡马克上的实验结果。
