| 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.
