An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed in Crookes tubes during experiments by the German scientist Eugen Goldstein, in 1886.[1] Later work on anode rays by Wilhelm Wien and J. J. Thomson led to the development of mass spectrometry.
