Abstract: An electron spectroscopy apparatus has an analyzer and a retardation lens system. In a first mode of operation, no retardation is applied, and the analyzer scans a low-energy range of the energy spectrum. In a second mode, retardation is applied, and the analyzer scans a high-energy range. The retardation is varied in synchronism with the scanning of the analyzer, so as to maintain a constant retardation factor.

Abstract: In a mass spectrometer having a magnetic analyzer, auxiliary ion beam control means comprising electrode structures which behave as electrostatic lenses are located externally of the magnetic analyzer to adjust the focal length of the ion beam to compensate for irregularities in the magnetic field of the magnetic analyzer caused by eddy currents induced in the analyzer during high speed scanning.

Abstract: A mass spectometer in which plural beams of ions can be generated simultaneously in separate sources. Convergent deflectors bring the beams close together for passage through an analyzer region. A divergent deflector separates an analyzed beam to provide adequate beam spacing for the positioning of detectors to respectively receive the beams.
