1869   Cathode ray tube
 

Plucker studies on electrical discharges in rarefied gases were continued by his pupil JW Hittorf <1> (1824-1914), using the pump Sprengel, was able to get pressure less than 0,001 mbar. Around 1869 determines that the electrical discharge in a vacuum tubes (or rarefied gas) are accompanied by "glow rays" (shining rays), which subsequently nominate 'cathode rays' (katodnih).  Always verify experimentally that katodnih are deflessi by magnetic or electromagnetic fields.
