摘要: Abstract The most economical way to increase the neutron intensity at an instument is optimization of all components that are responsible for extraction, moderation, transport, shaping and detection beam. Because principal interaction neutrons with matter nuclear magnetic origin, rely on diffraction, reflection, absorption by suitable materials. Recently, major breakthroughs in development artificial multilayers, monochromators, filters have improved performance scattering instruments significantly. In this contribution we discuss recent progress these fields some present future applications trends.
