摘要

总结。-由Forschungszentrum J¨ulich驱动的基于加速器的高亮度中子源HBS项目，预计将使用核Be(p,n)或Be(d,n)与较低MeV能量范围内的加速粒子反应。与散裂相比，较低的中子产量必须通过改进中子提取工艺和优化光亮度来补偿。慢化剂系统的设计和优化将通过MCNP进行，并将通过原型组件在AKR-2训练反应堆上进行测量验证，例如，将通过在线热容测量来研究和实时控制不同液体h2正对位比的影响。

Development of a moderator system for the High Brilliance Neutron Source project

Summary. — The project for an accelerator based high brilliance neutron source HBS driven by Forschungszentrum J¨ulich forsees the use of the nuclear Be(p,n) or Be(d,n) reaction with accelerated particles in the lower MeV energy range. The lower neutron production compared to spallation has to be compensated by improving the neutron extraction process and optimizing the brilliance. Design and optimiziation of the moderator system are conducted with MCNP and will be validated with measurements at the AKR-2 training reactor by means of a prototype assembly where, e.g. , the eﬀect of diﬀerent liquid H 2 ortho/para ratios will be investigated and controlled in realtime via online heat capacity measurements.
