  1. 16. High Electric field development for the SNS nEDM Experiment
    Dr Takeyasu Ito (Los Alamos National Laboratory)
    2017-10-18, 1:45 p.m.
    High voltage and electric field control (generation, leakage currents,...)
    Oral
    The SNS nEDM collaboration is developing an experiment to search for the neutron’s electric dipole moment (EDM), using ultracold neutrons (UCNs) stored in superfluid liquid helium, to be run at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. In this experiment, being able to achieve a strong and stable electric field in superfluid liquid helium in the region where UCNs...

  2. 30. Progress on the high-voltage and EDM cell studies for the TRIUMF neutron EDM experiment
    Dr Florian Kuchler (TRIUMF)
    2017-10-18, 2:10 p.m.
    High voltage and electric field control (generation, leakage currents,...)
    Oral
    The currently established best limit on the neutron EDM was obtained by eliminating and investigating main systematic effects using an atomic co-magnetometer inside the neutron storage volume. The next generation neutron EDM search at TRIUMF aims to introduce 129-Xe as co-magnetometer due to its low neutron absorption cross section. An optical detection scheme of 129-Xe spin precession is...

  3. 35. Statistical distribution of electrical breakdown in liquid helium
    Dr Nguyen Phan (Los Alamos National Laboratory)
    2017-10-18, 2:35 p.m.
    High voltage and electric field control (generation, leakage currents,...)
    Oral
    Realization of large electric fields is an important goal for neutron electric dipole moment (nEDM) experiments. For a nEDM experiment performed in superfluid helium such as the SNS nEDM experiment, it is vital to understand the behavior of high electric fields in this medium. The electrical breakdown, which limits the applicable electric potential and field, in liquid helium is poorly...
