Abstract
A photo cathode converts an incident light into photoelectrons. A photomultiplier kept vacuum inside thereof, amplifies photoelectrons converted by the photo cathode. Photoelectrons intensified by the photomultiplier arrives at an output electrode array, and a current signal produced by the photoelectrons arriving at the output electrode array is directly read outside the photomultiplier via metal bulbs or anisotropic conductive rubber.
