Nondispersive neutron focusing method beyond the critical angle of mirrors

摘要: This invention extends the Kirkpatrick-Baez (KB) mirror focusing geometry to allow nondispersive of neutrons with a convergence on sample much larger than is possible existing KB optical schemes by establishing an array at least three mirrors and appropriate multiple deflections via array. The method may be utilized supermirrors, multilayer mirrors, or total external reflection mirrors. Because high-energy x-rays behave like in their absorption reflectivity rates, this used as well neutrons.
