Spin-polarized electron source using a multiple microtip emission cathode, use in electron matter or electron particle interaction physics, plasma physics, electron microscopy

摘要

spin polarized electron source for using a cathode u00e9missive with microdots, application in physics of electrons or electron material particles, plasma physics, electron microscopy.;at least a portion (12) of each micropointe (10), and the top thereof is ferromagnetic, so that electrons emitted from the cathode (16) of a spin polarized direction, where each portion is subjected to a magnetic field parallel to the direction.
