tubes according to some fairly basic criteria. there are two primary distinguishing features, the source of free electrons within the device and the gaseous filling (or lack of it) within the tube envelope. the later of these two concepts we have already introduced by implication. a vacuum tube is a...
plücker and johann wilhelm hittorf , [ ] and were named in by eugen goldstein kathodenstrahlen, or cathode rays. [ ] [ ] in , british physicist j. j. thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the electron. cathode ray tubes...
