On easily tunable wide-bandpass X-ray monochromators based on refraction in arrays of prisms
Journal of Synchrotron Radiation, 2012 Refractive lenses focus X-rays chromatically owing to a significant variation of the refractive index of the lens material with photon energy. Then, in combination with an exit slit in the focal plane, such lenses can be used as monochromators. The spectral resolution obtainable with refractive lenses based on prism arrays was recently systematically ...

Novel idea of neutron polychromator and application for reflectometry and spectroscopy [PDF]
EPJ Web of Conferences, 2023 Historically, two methods have been used to determine the wavelength of neutrons: (i) a timeof-flight method that separates the velocity of pulsed neutrons by the flight time; and (ii) a method utilizing Bragg reflection by a monochromator, such as a ...
