Word History and Origins

Origin of anticathode¹

First recorded in 1905–10; anti- + cathode

Example Sentences

R�ntgen of Munich made in 1896 his remarkable discovery of the so-called X or R�ntgen rays, a class of radiation produced by the impact of the cathode particles against an impervious metallic screen or anticathode placed in the vacuum tube.

From Project Gutenberg

According to this theory the X rays should be due to a succession of independent pulsations of the ether, starting from the points where the molecules projected by the cathode of the Crookes tube meet the anticathode.

From Project Gutenberg

Thomson adopts an analogous idea, and states the precise way in which the pulsations may be produced at the moment when the electrified particles forming the cathode rays suddenly strike the anticathode wall.
