Query: Novel Concept for a Neutron Electric Charge Measurement using a
  Talbot-Lau Interferometer at a Pulsed Source   A concept to measure the neutron electric charge is presented which employs a
precision Talbot-Lau interferometer in a high-intensity pulsed neutron beam. It
is demonstrated that the sensitivity for a neutron charge measurement can be
improved by up to two orders of magnitude compared to the current best direct
experimental limit.
