P4-05: PHOTOMULTIPLIER TUBE - LARGE

PURPOSE: Show them what a large photomultiplier tube looks like.

DESCRIPTION: This is a large (8") photomultiplier tube which was once used in a particle physics experiment. The photocathode surface (on the inside front face of the tube), the focusing electrodes, and the dynodes are all easy to see.

SUGGESTIONS: Do not drop it. Because it is heavy and made of glass, it is probably not a good idea to pass it around the class.

REFERENCES: (PIRA unavailable.)

EQUIPMENT: Large phototube.

SETUP TIME: None.
