A high resolution ultraviolet monochromator HIRESUV for the study of disordered materials in the mesoscopic regime

We present the state of the art in the realization of a new spectrometer especially designed for high resolution and high-contrast scattering experiments in the ultra-violet (UV) spectral region. Different scattering techniques, employing neutrons, X-rays or visible light are compared with each other for transferred energies and momenta. The importance of high-resolution measurements in the UV range is stressed with particular attention devoted to the study of disordered materials. © 1999 Taylor & Francis Ltd.
