项目摘要

Up to now, the optimization of negative hydrogen ion sources for particle accelerators is mainly based on an empirical approach. The direct influence of the operational parameters or of individual components of the ion source on the discharge parameters of the hydrogen plasma is not considered, mainly due to the difficulties arising from accessing the sources with diagnostics. However, future accelerator experiments impose very high demands on the ion sources. In order to enable a dedicated optimization of the ion sources a detailed investigation of the discharge parameters and their influence on the negative hydrogen ion production is mandatory. This task is going to be covered by this proposed project, where a systematic analysis of the production and destruction processes of negative hydrogen ions and their dependence on the discharge parameters will be carried out. The insights gained from these fundamental investigations are going to be applied to the optimization of the Linac4 ion source at CERN which demanded ion current is not reached by any existing source up to now. It should be stated that the relevance of the investigations performed within this project is not limited to the Linac4 ion source. The insights gained from both the fundamental and the application-oriented investigations are of high importance for the world-wide development of the next generation of negative hydrogen ion sources.

到目前为止，粒子加速器负氢离子源的优化主要基于经验方法。不考虑操作参数或离子源的各个部件对氢等离子体的放电参数的直接影响，这主要是由于通过诊断访问源所产生的困难。然而，未来的加速器实验对离子源提出了很高的要求。为了实现离子源的专门优化，必须详细研究放电参数及其对负氢离子产生的影响。这一任务将包括在拟议的项目中，其中将对负氢离子的产生和破坏过程及其对放电参数的依赖性进行系统分析。从这些基础研究中获得的见解将被应用到欧洲核子研究中心的Linac 4离子源的优化中，该离子源要求的离子电流到目前为止还没有被任何现有的源达到。应该指出的是，在本项目中进行的研究的相关性不仅限于Linac 4离子源。从基础研究和应用研究两个方面获得的见解对下一代负氢离子源的全球开发具有重要意义。
