摘要：
The project for an accelerator based high brilliance neutron source HBS driven by Forschungszentrum Julich 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.
