Abstract
We present an improved instrument for the determination of the neutron electric charge with ultracold neutrons. Several technical upgrades with respect to a former experiment will be discussed in detail. As a first test, we applied the apparatus to investigate the influence of gravitational attraction by means of a massive block of lead. The calculated sensitivity for a charge measurement is δqnâ2.14Ã10â20e/day. Planned modifications increasing the sensitivity up to δqnâ1.34Ã10â21e/day are demonstrated.
