Oral Presentation

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...

8. High-voltage and electrode system for a cryogenic experiment to search for the neutron electric dipole moment

Oral Presentation

The cryogenic approach to the search for the neutron electric dipole moment—performing the experiment in superfluid liquid helium—holds promise for a substantial increase in sensitivity, potentially enabling a sensitivity level of $10^{−28}$ e cm. A crucial component in realizing such an experiment is the high-voltage and electrode system capable of providing an electric field of 75 kV/cm....

45. Comparison of roughness models in MCUCN simulations for n2EDM

Dr Geza Zsigmond (PSI - Paul Scherrer Institut)

Oral Presentation

Neutron particle-tracing simulations with the MCUCN code provide valuable insights into the expected ultracold neutron (UCN) performance of the n2EDM experiment at PSI, an input that also determines the statistical sensitivity. They also give reference estimates for further improvements to the UCN optics elements of the apparatus. One important aspect is the definition of the roughness...
