Low Energy Neutron Source (LENS)

Put your mouse over a blue link for more information.

The Low Energy Neutron Source (LENS) is a novel, university-based pulsed neutron source under construction at the Indiana University Cyclotron Facility. The facility will begin normal operations early in 2007. 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 and very cold neutrons for use by a suite of neutron scattering instruments and development facilities. For a general description of how the source works click here. More details about the various components of the source may be obtained by clicking on the structures of interest in the figure below.

LENS will be a regional university facility for research, innovation, education and outreach with a national impact. The emphasis on cold and very cold neutrons makes it suitable for materials research, particularly in the area of nanoscale structures which are a research focus of many universities in the region. The flexible scheduling and technical resources available at IUCF make it ideal for developing innovative new neutron scattering techniques and instrumentation that will provide national benefits. At the same time, LENS's location in a university environment supports educational development at a local, regional and national level.
