I was discovering a way to focus a number of charged particles which has been accelerated by Van de Graff generator into a beam.I do tried to find ideas in uniform magnetic field,but it seems I can only focus the particles onto a point rather than a beam.So here I was asking whether there had been any means discovered before?

Thanks.

For many particle accelerators, one "focuses" a beam of charge particles using quadrupole magnets.

Use google, there are plenty of good resorces out there. Then you can ask more specific questions if you enounter any problems.

If you don't find anything, I can give you a bunch of links to lecture notes.
