Description
The search for the neutron electric dipole moment relies on the interaction of a possible neutron electric dipole moment with an applied electric field. The n2EDM experiment is therefore designed to operate with a high voltage system capable of stable operation at the nominal electric field of 15 kV/cm with regular polarity reversals to maximize sensitivity while suppressing systematic effects.
This contribution presents the current status of the n2EDM high voltage system, including the power supplies, high voltage selector, feedthrough, electrodes and leakage current monitors. Commissioning results of operational performance of the system, recent developments, and planned upgrades are presented. We focus in particular on studies of leakage currents and spark events, which define acceptable operating conditions and guide further improvements of the system.
