Basic question on electron, ion and photon excitation

  1. Jul 21, 2008 #1
    everyone, I am not in this filed. So I get a simple question. Besides field emission and thermionic emission, is there any other means to excite the eletron and get electron beam. Could anyone tell me some basic similar ways to excite the ion and photon?

    Er... photoemission, as in the one that Einstein won the Nobel Prize for.

    What exactly do you mean by exiting "the ion and photon"?
