Abstract

The TRIUMF Ultra-Cold Advanced Neutron (TUCAN) collaboration aims at a precision neutron electric dipole moment (nEDM) measurement with an uncertainty of 10 − 27 e · cm, which is an order-of-magnitude better than the current nEDM upper limit and enables us to test Supersymmetry. To achieve this precision, we are developing a new high-intensity ultracold neutron (UCN) source using super-thermal UCN production in superfluid helium (He-II) and a nEDM spectrometer. The current development status of them is reported in this article.
在TRIUMF用超冷中子精确测量nEDM
TRIUMF超冷先进中子(TUCAN)合作旨在精确测量中子电偶极矩(nEDM),不确定度为10−27 e·cm,这比目前的nEDM上限好一个数量级,使我们能够测试超对称。为了达到这种精度,我们正在开发一种新的高强度超冷中子(UCN)源,利用超流氦(He-II)中的超热UCN产生和nEDM光谱仪。本文介绍了其发展现状。
