A. Sauer, H. Deitinghoff, H. Klein

摘要:

最近的离子源的发展导致产生高亮度,高电流束的质子和轻离子。提取和运输后,具有大的内部空间电荷力的束必须被捕获,聚束和预加速注入到以下驱动器的一部分,新一代的高强度束设施的中子源,能源生产,嬗变,例如,一个组合的的中子源和DTL被认为是一个很好的解决方案,这样的高电流离子注入器。一些初步的束流动力学布局进行了多粒子模拟研究。作为一个例子,对国际聚变材料辐照设施的设想,频率、离子能量和火花等基本参数都作了改变。主要的兴趣是针对高传输,低损耗和发射度守恒。简要地讨论了光束与反射镜的匹配以及反射镜与DTL之间的匹配。

英文摘要:

Recent ion source developments resulted in the generation of high brilliance, high current beams of protons and light ions. After extraction and transport the beams with large internal space charge forces have to be captured, bunched and preaccelerated for the injection into the following driver part of a new generation of high intensity beam facilities for neutron sources, energy production, transmutation e.g. A combination of RFQ and DTL is considered to be a good solution for such a high current ion injector. Some preliminary beam dynamics layouts have been investigated by multiparticle simulations. Basic parameters like frequency, ion energy and sparking have been varied for the International Fusion Material Irradiation Facility (IFMIF) scenario as an example. The main interest was directed to high transmission, low losses and emittance conservation. The beam matching to the RFQ is shortly discussed as well as the matching between RFQ and DTL.
