Performance Studies of High Gain Photomultiplier Having Z-Configuration of Microchannel Plates

Abstract

The characteristics of a high gain type ITT F4129 photomultiplier having three microchannel plates in cascade for electron multiplications have been investigated. These plates are in the Z-configuration. Measurements are given of the gain, dark current, cathode quantum efficiency, anode pulse linearity, electron transit time, single and multiphoton time spreads, fatigue, and pulse height resolution. The gain as a function of transverse magnetic field has been measured and is discussed. Photomultiplier characteristics as a function of the input pulse repetition frequency have also been investigated and discussed.
