Tesla 65PK423 photomultiplier

Description:

The photomultiplier is an extremely sensitive light detector, it can detect individual photons. The incoming light pushes electrons out of the sensitive layer. These electrons come into an electron multiplier which can amplify the signal in several orders of magnitude. This type was used in connection with a scintillation crystal which produces light when an ionising particle collides with it. The system was used as a radioactivity and high-energy particle detector in nuclear research.
