Abstract
A new high-performance electrostatic charged particle energy analyser has been developed with the purpose of combining all the diverse advantages of the currently available types of spectrometer into a single instrument. This paper indicates how the instrument evolved directly from the requirements of the design specification. The resulting device acts as a bandpass filter and consists of a retarding grid section, followed by an energetically dispersing region formed by a continuously decelerating, focusing field. Design aims, basic theory, construction and experimental evaluation are presented. Important performance parameters of the new design are its high signal-to-noise ratio, characterised by a high transmission (15%) and low spurious signal collection; high available energy resolution (0.03% FWHM); electrical adjustment of bandwidth; and comparative insensitivity to source position and external magnetic field. Capability to produce high-quality Auger spectra is demonstrated, emphasising the advantages of trade-off between spectral resolution and sensitivity.
