Rotghroth Rhapsody waterplant Posted March 13, 2010 Share Posted March 13, 2010 I am tempted to sound like I know what I'm talking about but I read about Ernest Lawrence and his 1931 'Cyclotron' in a National Geographic article about the recent CERN projects. '80 000-electron volt protons' sounds impressive but I can't claim to know what it means. Quote Link to comment Share on other sites More sharing options...
Magnificent Ornk Student of Trinity Posted March 13, 2010 Share Posted March 13, 2010 Huh — that's a lot more than I'd have guessed, but as far as I can tell from a bit of googling, that is indeed what Lawrence was able to get out of a device you could indeed hold in your hand. I wonder what its particle stream would actually do? 80 keV isn't enough to make any new particles; the lightest thing you can get would be a positron-electron pair, at just over a million eV. But you could certainly ionize a lot of atoms. And it seems you could easily get up to millions of eV with a tabletop cyclotron. So maybe a kit for kids to make real antimatter wouldn't be so impossible after all. Quote Link to comment Share on other sites More sharing options...

Seasoned Roamer The Ninjas Doom Posted March 13, 2010 Author Share Posted March 13, 2010 how do you burn hydrogen? Quote Link to comment Share on other sites More sharing options...
Well-Actually War Trall Niemand Posted March 13, 2010 Share Posted March 13, 2010 With Oxygen and a spark, about the same as anything else. It's pretty darn easy (at least in our Oxygen-rich atmosphere). Quote Link to comment Share on other sites More sharing options...
