title: Versatile electron spectrometer for surface studies.
abstract: An electron spectrometer is described which is designed to measure a variety of electron spectra of solid surfaces in ultrahigh vacuum. The instrument is capable of the high-energy resolution (10-15 meV) required for vibrational inelastic electron scattering from atoms and molecules on surfaces. It has also been designed to carry out angle-resolved photoemission measurements, Auger electron spectroscopy, and energy-loss measurements of electronic excitations. The performance of the instrument in these modes of operation is discussed.
