33. Development of a High Intensity Ultra-Cold Neutron Source using Superfluid Helium at TRIUMF

Mr Shinsuke Kawasaki (KEK)

2017-10-18, 9:00 a.m.

EDM experiment overviews

Oral

Ultracold Neutrons (UCN) are extremely slow neutrons with a kinetic energy in the order of 100 neV. As a consequence, UCNs are totally reflected at the surface of certain materials and can be confined in a material bottle. Using this unique property, UCNs are used for various experiments such as neutron electric dipole moment searches, neutron lifetime measurements, gravity experiments, and...

12. MC simulation efforts for nEDM experiment optimization and systematics calculations

Dr Geza Zsigmond (Paul Scherrer Institut)

2017-10-18, 9:35 a.m.

Simulation tools (Monte Carlo, finite elements, ...)

Oral

In UCN physics experiments Monte Carlo simulation methods are very effective in the characterization and optimization of many-parameter systems, and when a detailed calculation of a geometry containing several sub-volumes is relevant. Exact analytic modeling is not feasible in many cases - for example because of gravity effects on UCN or because of UCN viewing several surface qualities at the...

29. Monte Carlo optimization of a next-generation ultracold-neutron source

Dr Wolfgang Schreyer (TRIUMF)

2017-10-18, 10:00 a.m.

Simulation tools (Monte Carlo, finite elements, ...)

Oral

The TRIUMF Japanese-Canadian UCN Collaboration is planning a next-generation ultracold-neutron source. To maximize the number of ultracold neutrons available to experiments, Monte Carlo simulations of neutrons over a wide energy range are needed. Additionally, heat deposit due to neutron scattering, neutron capture, and gamma radiation is an important design parameter. This...
