The stream of electrons in a Crookes tube was long ago thought to be a ray, and the terminology is still a part of our language as in cathode ray tube which is often used as a synomyn for an ocilloscope tube or TV picture tube. Neil Ccpoodle 00:04, 5 April 2007 (UTC)

Did Crookes tubes ever use a filament?[edit]

I can't find any reference to Crookes tubes using a heated cathode, as the article and diagram show. These references describe Crookes tubes as cold cathode tubes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 The significant experiments on cathode rays using Crookes tubes, done by Hittdorf, Crookes, Goldstein, Plucker, Lenard, Rontgen, and J. J. Thompson, as far as I can tell, seem to have used cold cathode tubes. Although thermionic emission, the 'Edison effect', was discovered by Edison in 1880, and could have been used to generate cathode rays, it was a curiosity and not understood. Does anybody have any info about this? --ChetvornoTALK 18:20, 1 May 2008 (UTC)

Apostrophe in title[edit]

If Crookes invented this, then is it not Crookes' tube? —Anonymous DissidentTalk 12:45, 10 February 2009 (UTC)

In all the usage I've seen, Crookes' name seems to be incorporated as an adjective, rather than a possessive: "a Crookes tube" rather than "Crookes' tube". This is similar to other attributively-named inventions: "Edison phonograph", "Michaelson interferometer", "Doppler shift" or "Geiger counter". --ChetvornoTALK 22:58, 10 February 2009 (UTC)
Ah, I see what you mean. Fair enough. —Anonymous DissidentTalk 06:28, 11 February 2009 (UTC)

Naming the electron[edit]

This article says that J.J. Thomson named the electron. The article on George Johnstone Stoney says the he named the electron. Okay, who was it? Rsduhamel (talk) 00:10, 14 April 2009 (UTC)

At the time Stoney proposed the term electron, no particles smaller than the atom were known. Stoney's hypothetical positive and negative "electron" particles were a theoretical model to explain electricity, an alternative to the prevailing theory which was that positive and negative electricity were fluids, but there was no evidence for it. Thomson's work showed that cathode rays were tiny particles which were also responsible for other manifestations of electricity, confirming Stoney's theory, so he gave them the name "electrons". It's similar to how quarks were discovered: they were first invented as hypothetical particles in a theory by Murray Gell-Mann in 1963, and then the theory was slowly validated by experiments in the 70s and 80s. --ChetvornoTALK 22:35, 1 May 2009 (UTC)

Vanity Fair[edit]

What version of the device is Crooke's holding in this Vanity Fair cartoon? Drutt (talk) 09:01, 8 October 2009 (UTC)

I don't know; it looks a bit like one of the early Crookes x-ray tubes, which had heavy anodes to dissipate heat like the one on the L side of the tube. I'll check some early books. What a great picture! Why don't you add it to the article? --ChetvornoTALK 22:46, 1 December 2009 (UTC)

Amalgamation of Articles[edit]

The articles on Discharge tube, Vacuum tube, Crookes tube, and Geissler tube have a lot in common, and if amalgamated would give a better picture of the subject. Also, the history of these tubes needs the attention of an expert; the articles are somewhat Anglo-Saxon in outlook with little in-depth treatment of the German research in this area of over thirty years before Crookes. —Preceding unsigned comment added by 85.232.197.233 (talk) 17:57, 15 March 2010 (UTC)
