DEFINITION

Classification: 327/573

Electron multiplier type:

(under subclass 572) Subject matter wherein the secondary emissive type tube includes multiple electrodes (i.e., dynodes) which attract electrons freed from a light sensitive cathode and thereby increase the number of flowing electrons.
