CRT Discharge Tube development

Events

Pump

1855

German Geissler invents the Geissler tube, using the mercury pump to evacuate air in a vacuum tube, necessary for the production of cathode rays.

1st Cathode Rays

1859

German Julius Plucker conducted the first experiments with cathode rays.

Proof

1875

English Crookes was able to Confirm the existence of cathode rays by displaying them, with the Crookes tube, which was the basis for all developments for cathode ray tubes.

The Electron

1897

JJ Thomson was able to conclude and discover the existence of electrons by the experiments with Cathode rays. He exposed the beams with alternate and differing polarities and observed the deflections.

CRT Oscilloscope

1897

German Braun invented the CRT Oscilloscope, used for early TVs and current radar tubes.

TV! Sort of
