"Cold and Ultra-cold neutron studies at IUCF"
 Slideshow (PDF)
The Low Energy Neutron Source at Indiana University is a University-based long-pulsed source that makes use of a coupled solid methane moderator operating at temperatures below 10K. I will present recent results in which the moderator performance is compared to the predictions from our recently developed model for methane dynamics in the low temperature (Phase II). I will also present the UCN production in solid oxygen involving magnon (spin wave) exchanges which is fundamentally different from the well-known phonon mechanism in solid deuterium.
