Charged particle focusing device

motorman

Hi,

Is there a device that can attract alpha or beta particles and focus them on a point.

Something like the reverse of a CRT tube for electrons.

BR,

They can be attracted by negative or positive charges, respectively. Not to a single point, but to a small volume, if the conditions are right.
Why do you want to do that?
