Abstract :
An experiment searching for the neutron electric dipole moment by measuring spin-rotations in a non-centrosymmetric crystal was carried out to investigate the statistical sensitivity and systematic effects of the method. The preliminary result of this experiment is dn=(2.5±6.5)⋅10−24 e⋅cm. The performance was essentially limited by the low luminosity of the prototype setup. With a dedicated setup and a large quartz crystal, the expected accuracy is ∼2⋅10−26 e⋅cm for 100 days of data collection.
