quadrupole magnet

[Random Variable]

When they say that a quadrupole magnet can focus or defocus an electron beam, what the heck are they talking about?

I would imagine that they mean it can focus an electron beam or diffuse it.

or perhaps more effectively direct the path of electrons on a certain destinatiion or not.....

Sounds like a thread idea for the HT forum

Four poles = two pairs of pos/neg ?

perahps it can create a magnetic field in a ring of some sort that can direct the flow of electrons that pass thorugh it or scatter them by increasing the strength of the pos. vs. neg. ?

Man... when they come out with that ocho-pole magnet... man...

Oh God! What have I done? *runs to patent office*

it can either spread out or condense a stream of electrons

Thanks, Scoop!

Quadrupole will focus in one transverse plane, but defocus in the other transverse plane; if alternate, can have net focusing in both planes.

Translate, please.
