how do i shot electrons?

WITH THE EXPLOSIONS FROM MAGNETONS

okay, let me rephrase the question.
how do i shot electrons at relativistic speeds in a hand held device?

rail gun?

>>2 already told you, with magnets

http://en.wikipedia.org/wiki/Electron_gun
And if you're planning on making some sort of lightning gun... don't.

if i wanted a lightning gun i'd just build one of these instead: http://en.wikipedia.org/wiki/Electrolaser

i want to make one of these: http://en.wikipedia.org/wiki/Free_electron_laser

will an electron gun from a crt get the electrons moving fast enough for that?

The electron speed in CRTs is close to c. However, there's vacuum in there for a reason: electron beams dissipate *very* quickly in air, you won't hit anything with your gun.

Also, that hand held device will have to be plugged in, chances are you won't get it runnig with batteries.

The electron speed in CRTs is close to c.

"Typical kinetic energies coming off the cathode are on the order of 0.1 eV. After acceleration typical kinetic energies are 15-25 kEv, depending on the size of the CRT. The corresponding speeds are much less than c."

that won't be a problem, as the electrons only need to "hit" a magnetic field.

Yeah, i fucked up :/ Confused m/s with km/s....
The electron speed is only 0,31c for 25kEv.
