LENS: A new university-based neutron source for science and education

摘要

The low-energy neutron source (LENS) is currently under construction at the Indiana University Cyclotron Facility. LENS is a long-pulse neutron source utilizing low-energy (p,xn) reactions on a beryllium target to produce neutrons. There are several unique features of the LENS facility. The low proton beam energy of 13 MeV results in a low heat load on the moderator system, enabling the operation of the moderator at temperatures lower than 10 K. The low beam energies also result in relatively low activation of the materials surrounding the target and moderator, thus enabling rapid prototyping and turnaround times for a moderator studies program.
