Development of parallel plate channel multipliers for use in electron spectroscopy

Abstract: A simple method for designing parallel plate electron multipliers is described. Semiconducting and secondary emitting layers are deposited onto glassplates by rf-sputtering, and by placing two plates face to face with a separation of 0.6 mm a parallel plate multiplier is formed. The multipliers have a high gain (>10 9 ) and give output pulses with a very narrow pulse height distribution. The multipliers are used as detectors in electron spectrometers. The small dimensions imply that a large number of multipliers may be placed in the focal plane and used simultaneously.
