重离子聚变加速器概念需要小发射度、高电流束流。此类应用可能包括漏斗，其中高电流、同带电粒子束与双束电流交错，同时保持较小的发射度。最近在洛斯阿拉莫斯国家实验室完成了首次实验演示，证实了漏斗原理的光束动力学。成功测试了单腿原型 5-MeV、H{sup {minus}} 漏斗。这个单光束演示探讨了双光束漏斗的物理问题。它包含发射控制、位置控制和射频偏转元件，以及用于测量光束强度、位置和角度质心、能量和相位质心以及横向和纵向相空间分布的诊断元件。实验结果将与模拟进行比较。 7 参考文献，5 图。
Accelerator concepts for heavy-ion fusion require small emittance, high-current beams. Such applications could include funnels in which high-current, like-charged particle beams are interlaced to double beam current while retaining small emittances. The first experimental demonstration confirming the beam dynamics of the funnel principle was recently completed at Los Alamos National Laboratory. A single-leg prototype 5-MeV, H{sup {minus}} funnel was successfully tested. This single-beam demonstration explored physics issues of a two-beam funnel. It contained elements for emittance control, position control, and rf deflection, as well as diagnostics for measurement of beam intensity, position and angle centroids, energy and phase centroids, and transverse and longitudinal phase-space distributions. Results of the experiment will be presented along with comparisons to simulations. 7 refs., 5 figs.
