The violation of Baryon Number, $\mathcal{B}$, is an essential ingredient for the preferential creation matter over antimatter needed to account observed baryon asymmetry in universe. However, such a process has yet be experimentally observed. HIBEAM/NNBAR %experiment program proposed two-stage experiment at European Spallation Source (ESS) search number violation. will include high-sensitivity searches processes that violate by one or two units: free neutron-antineutron oscillation...
The European Spallation Source being constructed in Lund, Sweden will provide the user community with a neutron source of unprecedented brightness. By 2025, suite 15 instruments be served by high-brightness moderator system placed above spallation target. ESS infrastructure, consisting proton linac, target station, and instrument halls, allows for implementation second below We propose to develop high-intensity able (1) deliver larger total cold flux, (2) high intensities at longer...
Two methods for calibrating control rods are presented. A theoretical treatment is given of an oscillating technique and experimental results obtained by this method compared with those the rod bump-period method. second described whereby a neutron source suddenly removed from subcritical reactor levels before after change compared.
Abstract The kinetics of reactions the trifluoromethyl radical (CF 3 ) with several simple cations (Ar + , Xe O 2 NO CO C F 5 are studied via variable electron and neutral density attachment mass spectrometry (VENDAMS) technique. CF is produced dissociative to I, resulting in concentrations that smaller than using pyrolysis methods, but better quantified. Rate constants product branching fractions reported, typical uncertainties ∼ 30%. Three reactions, Ar proceed near calculated collisional...
Monte Carlo radiation transport codes have become the primary tool for shielding and activation analysis at high-powered spallation neutron sources. However, use of these to model facilities that large amounts requires variance reduction methods. This paper presents examples apply ADVANTG generated parameters analyses performed ESS using MCNP6. some limitations in be overcome little-known features used. The focus this is describe how were so other analyst sources can benefit from methods as well.
Abstract The U.S. Nuclear Regulatory Commission’s Guide 1.190 states that calculational methods used to estimate reactor pressure vessel (RPV) fluence should use the latest version of evaluated nuclear data file (ENDF). VITAMIN-B6 fine-group library and BUGLE-96 broad-group library, which are widely for RPV calculations, were generated using ENDF/B-VI.3 data, was most current when issued. We have developed new (VITAMIN-B7) (BUGLE-B7) libraries based on ENDF/B-VII.0. These libraries,...
