摘要:

为提高BNCT(硼中子俘获治疗)的超热中子产生效率,利用蒙特卡洛程序MCNP设计了一种基于低能电子加速器驱动中子产生器的结构,并对该结构模型各参数下的中子通量进行对比计算,找到能使超热中子通量达到最大值的最佳参数,并且计算了最佳模型下的中子能谱。初步模拟计算结果显示,该中子产生器的中子通量达到BNCT要求。

In order to improve the efficiency of epithermal neutron produced by Boron Neutron Capture Therapy (BNCT), we used MCNP code to establish a new type neutron generator based on Low energy electron accelerator and calculated neutron flux under each parameter of the structure model, which makes us find the optimal parameter that can maximize the flux of epithermal neutron. We also calculated the neutron energy spectrum based on optimal parameter. Preliminary simulation results show that the neutron flux of the neutron generator meets the requirement of BNCT.
