The NNBAR experiment aims to significantly improve the search for neutron to antineutron conversion at the European Spallation Source through advanced design and simulation efforts.
Contribution
This paper presents the conceptual design and simulation models for the NNBAR experiment, enhancing sensitivity by three orders of magnitude.
Findings
Design of moderator, reflector, beamline, shielding, and detector reported
Simulation models developed for optimization and sensitivity estimation
Progress towards a comprehensive conceptual design report
Abstract
The NNBAR experiment for the European Spallation Source will search for free neutrons converting to antineutrons with a sensitivity improvement of three orders of magnitude compared to the last such search. This paper describes progress towards a conceptual design report for NNBAR. The design of a moderator, neutron reflector, beamline, shielding and annihilation detector is reported. The simulations used form part of a model which will be used for optimisation of the experiment design and quantification of its sensitivity.
