It aims to detect the neutron's presumed EDM by looking for changes in the light emitted when cold neutrons interact with helium - 3 nuclei in the presence of an electric field, a process that is subtly altered if the neutron has an EDM.

It uses liquid helium to cool neutrons to almost absolute zero, then observes whether their behaviour changes in an electric field.
