The High Brilliance neutron Source (HBS) is a project for next generation research facility, based on new concepts and recent technological advancements. As elementary processes it uses neither fission nor spallation, but instead low energy nuclear reactions in very compact Target-ModeratorReflector (TMR) assembly. Our facility design results efficient production of beams with high brightness. Key features HBS are: (i) competitive instrument performance, (ii) comparatively construction...
The goal of the “Workshop on Very Cold and Ultra Neutron Sources for ESS” was to discuss scientific cases, ideas possibilities implementation sources neutrons at European Spallation Source. ESS facility, presently under construction, offers several in-pile UCN or VCN sources, in primis thanks available space below spallation target where additional neutron can be placed complement those above target. beams extracted over a wide angular range with grid forty-two beamports 6° average...
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%.
The main, high-brightness neutron source for ESS is based on the low-dimensional moderator concept, and will serve initial suite of scattering instruments. In HighNESS project several design options have been identified investigated a second ESS, intended to be complementary primary one. emphasis this project, completed in September 2023, was high-intensity sources, delivering Cold, Very Cold (VCN), Ultra-Cold Neutrons (UCN). Remarkable results include: cold liquid deuterium capable an...
