Intro: This electronic poster of my work will be presented in three
section. The first will give general definitions of terms used in
the rest of the presentation. The second section covers the A-correlation experiment
and this project's role in it. The final section gives an overview
of the work being done at Virginia Tech. The pages are linked sequentialy,
and they can also be accessed from the section headings below. Other
links on this page also relate to the Virginia Tech group and the experiment
as a whole.
Abstract: The goal of this work is to obtain the best possible guides
for transporting and storing polarized ultracold neutrons (UCN) for use
in beta decay asymmetry experiments at LANSCE. To achieve this goal guides
are made by depositing diamond-like carbon (DLC) inside quartz tubes via
pulsed laser deposition of pyrolitic graphite. This technique yields guide
surfaces which are smooth and highly reflective for UCN. The current state
of guide development as well as DLC critical velocity, obtained by neutron
reflectometry, and guide roughness will be presented.
