Abstract

In this paper the estimation of the neutron yield in ⁷Li(p, n)⁷Be reaction was performed. Energy losses in neutron generating targets for ion beams with wide energy spectra were calculated using SRIM software. Lithium, lithium fluoride and lithium oxide were considered as target materials. The maximum numbers of protons per cm² were calculated for the materials under the condition of a thermally insulated targets in restrictions of melting and vaporization of the targets. The total neutron yield for pulsed proton beams was evaluated in comparison with a continuous proton beam.

基于脉冲功率质子加速器的7Li(p, n)7Be反应中子源中子产率估算

本文对7Li(p, n)7Be反应的中子产率进行了估计。利用SRIM软件计算了宽能谱离子束产生中子靶的能量损失。考虑了锂、氟化锂和氧化锂作为靶材料。在靶材具有绝热条件下，在限制靶材熔化和汽化的条件下，计算了材料每平方厘米的最大质子数。通过与连续质子束的比较，对脉冲质子束的总中子产率进行了评价。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
