Laue diffraction method of a neutron EDM search. Project of the experiment

Experiment for the search for the neutron electric dipole moment using Laue diffraction in a noncentrosymmetric crystal is proposed. The method is based on the effect of depolarization of the diffracted neutron beam due to interaction with an interplanar electric field of a noncentrosymmetric crystal. The value of this field can exceed ∼10 8 V/cm . An essential feature of the proposed Laue diffraction method is the possibility to increase more than by the order of value the time τ of neutron passage through the crystal and, accordingly, the time of interaction with the electric field using the Bragg angles close to π/2. The sensitivity of the method can be ∼10 −25 e cm / day for a really existing quartz crystal.
