论文摘要
在本文中，我们报告了具有基于狭缝的系统的高电流密度离子光束谱诊断，可靠，能够具有高热负载应用。该任务是在中子X线摄影的点状中子源开发的框架内出现的。在先前的研究中，有人建议基于高电流煤气离子源来构建这样的系统，该系统利用强大的毫米波旋转辐射使用的电子回旋谐振放电的等离子体。该设备能够产生聚焦的D+梁，其特征直径为1 mm，总电流高于100 mA，电流密度在几个A/CM^2的水平下。对这种强烈的光束轮廓的研究以获得最佳的聚焦效率并最大程度地减少中子产生区域似乎是一项艰巨的任务。该论文还证明了使用点状强大的中子发生器（10^10 1/s的中子产量）的快速中子成像的可能性。
In this paper we report on a high current density ion beam profile diagnostics with a slit-based system as a reliable method, capable of high thermal load applications. The task arose in frames of a point-like neutron source development for neutron radiography. In previous research, it was suggested to construct such a system as a D-D neutron generator based on the high current gasdynamic ion source, which utilises the plasma of electron cyclotron resonance discharge sustained by powerful millimeter wave gyrotron radiation. This device is able to produce focused D+ beams with a characteristic diameter of 1 mm, total current above 100 mA, and current density at a level of several A/cm^2. Study of such intense beams profile to obtain the best focusing efficiency and minimize neutron producing area appeared to be a challenging task. The paper also demonstrates the possibility of fast neutron imaging with a point-like powerful neutron generator (neutron yield on the level of 10^10 1/s).
