摘要

精确的加速器网格对准是决定多孔径粒子束性能的一个重要因素。这对于JET正离子中性注入器(PINIs)尤其重要，其中加速器由两个网格组成。网格错位会导致束流拦截元件的功率负载增加，束流传输减少，最终导致注入等离子体的中性束流功率减少。JET最近开发了一种新的PINI加速器装配程序，该程序利用机械臂测量装置。PINI对准数据被用作光束模拟代码的输入，用于在中性光束试验台进行测试之前预测光束特性。由于新的PINI组装程序和相关的计算机代码已经实现，JET PINI的对齐已经大大改善。

Influence of accelerator grid misalignment on multi-aperture particle beam properties

Accurate accelerator grid alignment is a major factor governing the properties of multi-aperture particle beams. It is particularly important for JET positive ion neutral injectors (PINIs), where accelerators are constructed of two grid halves. Grid misalignment can lead to increased power loading of beam intercepting components, to reduced beam transmission, and, finally, to reduced neutral beam power injected into plasma. A new PINI accelerator assembly procedure, which utilises a robotic arm measuring device, was recently developed at JET. PINI alignment data are used as input to a beam simulation code to predict beam properties prior to testing at the Neutral Beam Test Bed. Since the new PINI assembly procedure and the associated computer code have been implemented the alignment of JET PINIs has been considerably improved.

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
