Re: Protons
The high voltage of the Duoplasmatron http://books.google.com/books?id=v9SoaC ... q=&f=falserips the electron off the hydrogen molecule leaving a single proton that is injected in to the PS .
Re: Protons
Hydrogen is a proton with an electron flying around it - nothing more (excluding the very rare isotopes, which also have a neutron or 2). So as Harbles said, rip iff the electrons and all you're left with is a bunch of free protons! Gaseous hydrogen (H2) will be broken up in this process, as it is the electrons forming the bond between atoms.Sphereix8 wrote:Does anyone have an understanding of how the proton source works? I've seen pictures of hydrogen bottles on the linacs listed as the proton source, but I don't see how they extract the protons from the hydrogen.
Does anyone know how (if?) they get rid of the 2H and 3H isotopes for those bottles? Though I assume they'd be unable to keep up with the main proton stream (due to extra mass), so it may not matter?

Re: Protons
I'd expect most of the D2/T2 to have been removed before the gas was bottled, as these have uses elsewhere.
Eitherway, any stray D/T would probably be "left behind" as you said Danny. They won't follow the same curvature in a magnetic field either, so would impact against the sides of the beam tubes quite early on.

Re: Protons
Wow Harbles.
You instantly found a book on the subject AND you used the word "Duoplasmatron" which is I think what powers all 1950's scifi movie space ships.. Or sure should have.

Re: Protons
Harbles, thanks for the link, great read, question answered. Danny252, thanks captain obvious
Re: Protons
You never know - some people think the LHC has electrons and antiprotons, never mind knowing what Hydrogen is!Sphereix8 wrote:Harbles, thanks for the link, great read, question answered. Danny252, thanks captain obvious
Re: Protons
Your right, it's good information for those that don't know, and this is a great place to learn it! MORE FREE KNOWLEDGE!!!!You never know - some people think the LHC has electrons and antiprotons, never mind knowing what Hydrogen is!
Re: Protons
If you have not wandered around the doc server, its like the ultimate in free knowledge..

Re: Protons
And this thread provokes the question.. yeah but what about lead ions?
LEIR

What's an ECR? Electron sumthing sumthing that generates lead ions from a lump of lead.
*edit
Electron Cyclotron Resonance.
Who'd have thunk it. had to ask the Japanese to spell it out.

Missed it on wiki 1st time around.
