A global approach coupling the moderator to beam extraction system has been applied for design optimization of thermal and cold moderators European Spallation Source (ESS), which will be brightest neutron source in world condensed-matter studies. The is based on recently developed high-brightness low-dimensional concepts. Para -hydrogen used source, while neutrons are provided by moderation water. overall configuration was chosen order satisfy a range requirements bispectral extraction,...
In a recent numerical optimization study we have found that liquid para-hydrogen coupled cold neutron moderators deliver 3–5 times higher brightness at spallation source if they take the form of flat, quasi 2-dimensional disc
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...
Abstract The NNBAR experiment for the European Spallation Source will search free neutrons converting to antineutrons with a sensitivity improvement of three orders magnitude compared last such search. This paper describes progress towards conceptual design report NNBAR. moderator, neutron reflector, beamline, shielding and annihilation detector is reported. simulations used form part model which be optimisation quantification its sensitivity.
A key aim of the HighNESS project for European Spallation Source is to enable cutting-edge particle physics experiments. This volume presents a conceptual design report NNBAR experiment. would exploit new cold lower moderator make first search in over thirty years free neutrons converting anti-neutrons. The observation such baryon-number-violating signature be fundamental significance and tackle open questions modern physics, including origin matter-antimatter asymmetry. shows beamline,...
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 European Spallation Source (ESS), presently under construction in Lund, Sweden, is a multidisciplinary international laboratory that, once completed at full specifications, will operate the world's most powerful pulsed neutron source. Supported by 3 M Euro Research and Innovation Action within Union Horizon 2020 program, design study (HighNESS) now underway to develop second source located below spallation target. Compared first source, which above target designed for high cold thermal...
The European Spallation Source will have 42 beam ports as a grid available for variety of instruments, mostly neutron scattering experiments. Bi-spectral extraction thermal and cold neutrons must be to all the ports. moderator design deliver such beams was driven by low-dimensional concept. adopted design, consisting one flat (3 cm high) placed above spallation target considered valid initial instruments suite. ESS however port system designed that it possible extract from moderators below...
The TRiga Accelerator-Driven Experiment (TRADE), to be performed in the TRIGA reactor of ENEA-Casaccia Centre Italy, consists coupling an external proton accelerator a target installed central channel scrammed subcriticality. This pilot experiment, aimed at global demonstration accelerator-driven system concept, is based on original idea C. Rubbia. present paper reports results some neutronic analyses focused feasibility TRADE. Results show that all relevant experiments (at different power...
