<title>Hybrid phototube with Si target</title>

Abstract

Research and development programs for future supercollider detectors require photomultipliers that offer high speed, good linearity, wide dynamic range, a good stability, and do not need bleeder resistance networks. It has been demonstrated that a hybrid photomultiplier, being a vacuum phototube in which the photoelectrons are focused onto a Si PIN diode, fulfills these requirements. The next step is a multipixel tube adding position sensitivity to the detector.
