Apparatus for measurement of the electric dipole moment of the neutron using a cohabiting atomic-mercury magnetometer

摘要

A description is presented of apparatus used to carry out an experimental search for an electric dipole moment of the neutron, at the Institut Laue-Langevin (ILL), Grenoble. The experiment incorporated a cohabiting atomic-mercury magnetometer in order to reduce spurious signals from magnetic field fluctuations. The result has been published in an earlier letter ; here, the methods and equipment used are discussed in detail.
