Design and fabrication of an indigenous molecular beam ultraviolet photoelectron spectrometer

Abstract

An ultraviolet photoelectron spectrometer for the study of van der Waals molecules has been designed and fabricated indigenously. The spectrometer consists of an Hel discharge lamp, a molecular beam sample inlet system, an electrostatic lens, a 180° hemispherical electrostatic analyser and a channeltron detector. Performance of the spectrometer is illustrated with an example.
