ABSTRACT:
A long photomultiplier comprises a cylindrical main body having a light receiving face which extends in the longitudinal direction of the main body, a photocathode provided inside of the main body so that the photocathode extends along the light receiving face and emanates photoelectrons when exposed to light, and dynodes provided inside of the main body for multiplying the emanated photoelectrons. A reflection plate is provided facing and extending along the light receiving face, and the photocathode is positioned between the light receiving face and the reflection plate. The reflection plate is positioned for reflecting light, which has passed through the photocathode, toward the photocathode.
