The neutron yield for compact accelerator driven sources depends on the target material, ion type and its energy. When such are operated with low energy proton beams below 30 MeV, typical materials lithium beryllium. New developments indicate that higher energies or a deuteron beam might be useful to increase at constant power. Here we present total analytically calculated protons deuterons up 100 MeV various materials. involved cross sections stopping power of material. This study shows...
The proposed High Brilliance Neutron Source (HBS), recognized within the Helmholtz Association of German Research Centres, will optimize entire chain from particle source through accelerator, target, moderator, reflector, shielding, beam extraction, transport all way to detector, utilizing nuclear Be(p,n) or Be(d,n) reaction in lower MeV energy range. A D2O moderating reflector prototype (MRP) and a cold were constructed build according MCNP parameter studies. MRP was tested feasibility...
Neutrons are an essential tool in science and research for probing the structure dynamics of matter from mesoscale to picoscale seconds femtoseconds.To release neutrons ...
The neutron yield for beryllium, vanadium and tantalum irradiated with 22, 27, 33 42 MeV protons is indirectly determined by Prompt Gamma Neutron Activation Analysis (PGNAA). neutron-to-gamma conversion rate measured an AmBe calibration source. Corrections escaped neutrons are applied via MCNP simulations of the experiment using ENDF/B-VII.1 database. experimental results in good agreement obtained from deviating 0.4% to 13%.
We investigate the potential of neutron scattering instrumentation fed by a compact accelerator driven source.Such source can be built and operated easily at any large university.Reference designs typical workhorse instruments for small-angle scattering, powder diffractometry reflectometry are presented.The flux sample position instrument resolution have been calculated from parameter design pulsed with 400 W average power.Instrument performances allow reasonable scientific use even this low...
