Neutron Moderator Development Research at the Low Energy Neutron Source

The Low Energy Neutron Source at Indiana University completed its construction phase roughly three years ago, and one of the more active research thrusts at the facility since that time has been our attempts to advance the state of the art in neutron moderation. This research program includes basic materials characterization, especially total neutron cross section measurements, as well as in-situ testing of the performance of various prototype moderators. This paper reviews a number of the more noteworthy results we have uncovered and describes the goals of the moderator development program at LENS. © 2011 Published by Elsevier Ltd.
