Transport Simulation towards Understanding the Field-Dependent Ultracold Neutron Production in Solid Oxygen

ORAL

Abstract

We will present a Monte-Carlo simulation on ultracold neutron (UCN) transport in the guide system used in the UCN production experiment in the summer of 2008. The simulation uses a UCN package [1] previously developed at Paul Scherrer Institute using the GEANT4 framework. The resulting transport efficiency is benchmarked by measurements on UCN transport through the same guide system. Furthermore, we simulate UCN transport through a non-uniform, solenoid magnetic field, results of which are used to extract the information of field-dependent UCN production in Solid Oxygen in low temperature alpha- and beta- phases.
