A gating large area hybrid photomultiplier tube that includes an envelope, a photocathode for emitting electrons in correspondence with incident light entering the envelope, a collecting anode having a semiconductor device which has an electron incident surface for receiving photoelectrons emitted from the photocathode, a gating grid for gating the photoelectrons emitted from the photocathode, an electron optical system for focusing and directing the photoelectrons generated by the photocathode toward the electron incident surface, and an ion target for collecting positive ions from the photoelectrons. The envelope has a first opening and a second opening; the photocathode is disposed at the first opening, while the collecting anode is disposed at the second opening of the envelope.

Gating large area hybrid photomultiplier tube

A large area hybrid photomultiplier tube that includes a photocathode for emitting photoelectrons in correspondence with incident light, a semiconductor device having an electron incident surface for receiving photoelectrons from the photocathode, and a cone shaped container. The container has a first opening and a second opening. The photocathode is disposed at the first opening, and the semiconductor device is disposed at the second opening.
