Abstract
A photomultiplier includes a cascade of microchannel plates which are physically and electrically connected to provide an electron multiplication through the microchannel cascade. One of the microchannel plates is a high-output microchannel plate providing a high level of electron multiplication. This high output microchannel plate is thermally conducted to ambient by a heat transfer path including outwardly disposed microchannel plates in the cascade. A unitary ceramic housing defines a vacuum envelope for the photomultiplier.
