Who developed the Betatron[edit]

It's been a while since I researched this, but it is my recollection that Steenbeck developed the theory but didn't get his device to work. I think his design had some issues. I recall it was like a standard power transformer with a rectangular core -- wires were wrapped around one side and the vacuum chamber was around the other. Dlenmn 22:18, 3 June 2007 (UTC)

I think you should edit the part about who developed the Betatron:

The articel in the german wikipedia says: german betatron articel

"The first Betatron was developed by Max Steenbeck in 1935 at the Siemens-Schuckertwerk laboratory in Berlin. But it was kept secret in the first years ...[...] ... Independet of this Betatron, Donald William Kerst build an Betatron in 1940 at the University of Illinois, so thats why he is todays inventor of the betatron, but also he refers in his publications in the Physical Reviwe to Rolf Wideroe, he had the ideas for the Betatron already in 1920s."

This is only a rough translation of this paragraph: Das erste funktionsfähige Betatron wurde 1935 von Max Steenbeck im Forschungslabor der Siemens-Schuckertwerke Berlin entwickelt, jedoch zunächst geheim gehalten und wegen anderer Schwerpunktsetzungen nicht weiterverfolgt. Unabhängig davon wurde ein Betatron 1940 auch von Donald William Kerst an der University of Illinois gebaut, der daher heute als Erfinder des Betatrons gilt, sich jedoch auch in seiner Veröffentlichung im Physical Review ausdrücklich auf Rolf Wideröe bezog, der die Idee zum Betatron bereits in den 1920er Jahren hatte.

I commented on the subject article to bring attention to the following statement:

§ "a Betatron was also used to provide electrons converted into neutrons"

... which is nonsense. As I wrote, there is no process by which electrons are converted to neutrons. The weapon-test cited in the article clearly states (correctly) that the Betatron's electron-beam was used to generate high-energy X-rays (NOT NEUTRONS) which initiated fission.

Michio Kaku[edit]

It says in the text that Michio Kaku tried to build a betatron while in High School. He only built a large electromagnet so I really don't think that it could count even as _trying_ to build a particle accelerator...

I tried to build a sun while in elementary school, but I only did the drawing :)

In other words, I really believe that it is totally irrelevant to mention the above in the text. — Preceding unsigned comment added by Bjornebarn (talkcontribs) 08:59, 26 December 2012 (UTC)

The funny long name[edit]

The articles says "Außerordentlichhochgeschwindigkeitelektronenentwickelndenschwerarbeitsbeigollitron", which is not correctly copied from the source. There, it is "Ausserordentlichhohegeschwindigkeitselektronenentwickeldenschwerarbeitsbeigollitron" which also has a typo ("...entwickelden..." -> "...entwickelnder..."). If the sources has quoted from memory or from an oral discussion among colleagues, it probably missed some spaces. The term "Ausserordentlichhohegeschwindigkeitselektronen entwickelnder Schwerarbeitsbeigollitron" is easy to understand. Perhaps someone with access to the source can find the 'friend' who suggested the name.

I hope we can solve this important matter. — Preceding unsigned comment added by 2003:71:6F0C:D00:1109:B5E1:FCA7:DE1A (talk) 12:24, 20 November 2015 (UTC)
