Abstract

A 24 anode linear-array of fine-mesh photomultiplier tube is shown to produce a clear single-photon peak in its pulse-height distribution under strong magnetic field of B≤1 T. This is possible by shortening the distance between the photocathode and the first dynode to 1 mm and using a finer mesh size of 2500 lines/in with 4 μmπ. This tube provides σTTS = 100 ps of transit time spread and 85% of photoelectron detection efficiency.
