Abstract

Abstract:

A set of electric deflection structure for EAST neutral beam injector was designed, and the core parameters of the system were estimated. The electric deflection system can meet the requirement of 80keV deuterium ion beam deflection under deflection field formed by 4.41kV deflection voltage. In the deflection field modulation, the electric deflection system can effectively reduce the heat load of the ion dump. Thus, it is very easy to meet the need of steady state operation for EAST neutral beam injector.

Key words: Neutral beam, Deflection system, Electrical deflection, Neutral beam injector

摘要：

为EAST 装置中性束注入器设计了一套用于将剩余离子在线电偏转的结构，并对系统各设备的核心参数进行了估算。在4.41kV 偏转电压作用下，该电偏转系统可提供80keV 氘离子束偏转所需的偏转电场。在偏转电场调制情况下，该电偏转系统可有效降低极板表面的热负荷，进而满足EAST 中性束注入器稳态运行的需要。
