为研究与核天体物理有关的聚变反应，建造了一台小型低能强流加速器。它由一个改进的NANOGUN™，一个低能束传输，一个无窗气体靶，一个束量能器和一个探测器系统组成。该加速器和NANOGUN离子源具有单个引出电极，在气体靶室中提供930 μA的20 keV的3He1+。已经针对几个源电压测试了双电极提取。在20、25、30、35、38、40和45 kV电位下，获得的目标电流分别为75、140、110、110、105、78和80 μA。从源到目标的传输效率为5.7%。
A compact low-energy, high current accelerator has been constructed for the study of fusion reactions relevant to the field of nuclear astrophysics. It consists of a modified NANOGUN™, a low-energy beam transport, a windowless gas target, a beam calorimeter, and a detector system. The accelerator and the NANOGUN ion source with a single extraction electrode provides 930 μA 3He1+ of 20 keV at a gas target chamber. A two-electrode extraction has been tested for a few source voltages. The obtained target current is 75, 140, 110, 110, 105, 78, and 80 μA for 20, 25, 30, 35, 38, 40, and 45 kV potential, respectively. The transport efficiency from the source to the target is 5.7%.
