The Low Energy Neutron Source (LENS) is a pulsed neutron source at the Indiana University Center for Exploration of Energy and Matter (CEEM). The source utilizes a low energy p-n reaction in Be coupled with a high-current, variable-pulse-width proton accelerator to produce either short or long neutron pulses. A highly optimized moderator produces cold neutrons for use by a suite of neutron scattering instruments and development facilities.
Major ongoing activities include the development of new neutron instrumentation (in particular for neutron spin manipulation and improved moderators), large scale structure studies in materials using small angle neutron scattering (SANS), spin echo scattering angle measurement (SESAME), and neutron radiation effects.
