Abstract

A serious problem in the measurement of the ultraviolet reflectivity of solids at helium temperatures is the prevention of condensation of contaminants on the samples. This paper describes a shielding arrangement for a reflectometer which effectively prevents such contamination and permits reliable measurement of the reflectivity up to photon energies of 12 eV. This system required that a McPherson spectrograph be modified.
