  • 摘要: 兰州大学设计研发的ZF-400强流中子发生器设计D-T中子产额6×1012 n/s,主要由ECR离子源、低能束流传输线(LEBT)、加速管、旋转靶等部分组成。LEBT负责将从离子源引出的束流进行分析聚焦并注入到加速管中。LEBT对束流的聚焦及分析的好坏程度决定了加速管中束流的损失程度、中子的产额以及靶的寿命。本工作就该强流中子发生器所需的低能传输线进行了设计。使用螺线管、分析磁铁和四极透镜组合的方案。利用TRACK软件对此方案进行模拟,得到符合要求的束流线及元件的参数。用TraceWin进行了验证模拟,验证结果符合要求。另外,通过软件模拟确定了杂质离子损失的位置,据此设计了束流管道冷却方案。通过模拟发现,这种透镜的组合方式可以让整个LEBT以较低的功率获得低损失、高纯度的打靶束流。


    The ZF-400 Intense Neutron Generator, which is designed by Lanzhou University with an expected neutron yield of 6×1012 n/s, is consist of ECR ion source, low energy beam transport (LEBT) line, accelerating tube and rotating target. The beam extracted from ECR source is analyzed and focused through LEBT, then, the beam is introduced into the accelerating tube. The focus and analysis ability of LEBT is very important for the beam loss, neutron yield and target's life. A LEBT line for intense neutron generator is designed in this paper, the project consisted of a solenoid, a bend magnet and three quadrupole lens. The qualified LEBT and its parameters have been got through the simulation with TRACK code. Then TraceWin program was employed to check this simulation and the result satisfied our requirement. Besides, the loss position of impurity ions was known through the simulation, and a project of beam line's cooling system was designed according to this result. Through the simulation, we find the optimal lens combination plan which can obtain lower beam loss and higher beam purity at low running power of LEBT.
