Special Issue on Neutron Scattering

The articles in this issue review the current status of neutron‐scattering facilities in the US and abroad, discuss in more depth some recent contributions of neutron scattering to fundamental studies of condensed matter—including biophysics—and suggest future scientific opportunities in these fields. The photo at right shows one of the sources that makes all these studies possible: the core of a reactor. Neutrons from fission reactions here are transported out of the reactor, collimated, and sent to scatter off a sample. This particular reactor is the High Flux Beam Reactor at Brookhaven National Laboratory.
