A cylindrical mirror analyser is used for angle-resolved electron spectroscopy by projecting the cone of accepted electrons on to a position-sensitive detector placed behind the exit aperture of the analyser. Each electron is amplified by a double micro-channel plate and its azimuth is determined from the ratio of two charge pulsed arriving at the ends of a capacitor chain coupling 39 separate anodes. The azimuthal distribution is collected in a computer-controlled multi-channel analyser. Electrons are focused on the detector by a newly developed electron lens which improves sensitivity and resolution of the system.
