摘要
提出适合硼中子俘获治疗加速器7Li(p,n)7Be反应中子源的一个金属锂靶的设计,并对中子产额进行了计算。用MonteCarlo的方法研究了中子在水中的慢化和反射层对中子能谱的影响。结果表明,在这种几何结构下7Li(p,n)7Be反应产生的中子经过5cm的水层慢化后可作为硼中子俘获治疗的超热中子源。
A design of metal Lithium target for accelerator 7 Li (p,n) 7 Be reaction neutron source is proposed,and neutron yield is calculated.The moderation of neutron in light water and the impact of neutron reflector on neutron spectrum are investigated with the Monte Carlo method.It is concluded that neutrons produced by accelerator with 7 Li(p,n) 7 Be reaction and then moderated by light water of5cm thickness can be used as the epithermal neutron source of boron neutron capture therapy.
