CYCIAE-14回旋加速器为了实现高流强,采用外部负氢多峰离子源和轴向注入方式。能量为25keV的H-束流从位于加速器上方的离子源引出后,经过注入线轴向向下注入螺旋偏转板入口,偏转90o后到达加速器的中心平面。在中心区,通过构建和调整电极结构和高频腔头部结构,实现与螺旋偏转板出口束流的匹配,使束流接收度达到最大。1中心区的设计中心区的设计是一个要实现多重目标的任务,主要设计目标有:偏转板出口附近实现束流匹配,
The CYCIAE-14 cyclotron uses an external negative hydrogen multimodal ion source and axial injection for high flow rates. The H-beam with 25 keV energy is extracted from the ion source located above the accelerator and then injected axially down the inlet of the helical deflector through the injection line and deflected by 90 ° to reach the central plane of the accelerator. In the central area, the structure of the electrode and the structure of the head of the high frequency cavity are constructed and adjusted to achieve the matching with the exit beam of the spiral deflector, so that the beam receiving degree is maximized. Design of a center area The design of a center area is a task to achieve multiple objectives. The main design goals are: to achieve beam matching near the exit of the deflector,
