论文摘要

与上一次这样的搜索相比，欧洲散布源的NNBAR实验将搜索自由中子，以提高三个数量级的敏感性。本文描述了NNBAR概念设计报告的进展。报道了主持人，中子反射器，梁线，屏蔽和歼灭探测器的设计。使用的模拟构成了模型的一部分，该模型将用于优化实验设计和量化其灵敏度。

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.
