Abstract

A neutron source composed of a tandem accelerator with vacuum insulation and a lithium target is used to develop the boron neutron capture therapy and other applications. The dependence of the proton beam size on the target surface on the beam current is measured with thermocouples inserted inside the target and with a infrared camera. It is found that there is no appreciable influence of the spatial charge on the proton beam transport to a distance of 5 m from the accelerator to the target, which simplifies the neutron source operation.

基于加速器的超热中子源中2-MeV质子束传输的空间电荷效应研究

摘要

由具有真空绝缘的串联加速器和锂靶组成的中子源被用于开发硼中子俘获疗法和其他应用。质子束大小在靶表面上对束流的依赖性通过插入靶内部的热电偶和红外热像仪进行测量。已经发现，空间电荷对质子束传输至从加速器到目标的距离为5 m的距离没有明显影响，这简化了中子源的操作。
