ABSTRACT:
A multi-channel photomultiplier tube in which light radiation from distinct sources passes through an entrance window to a photo-cathode, the window being divided into parts so that light from a source passes through a respective part to an associated part of the photo-cathode, the division of the window into parts constraining the light from incidence upon other parts of the photo-cathode.
