<p>PURPOSE:To provide a polarized electron beam generating device which is compact and easily handled. CONSTITUTION:A laser beam source 12, a 1/4 wavelength plate 14, a light amplifier 16, and a polarized electron beam source 18 are integrally disposed in a single housing 22, and a laser beam radiated from a laser beam source 12 is applied to a back surface of the polarized electron beam source 18, so a polarized electron beam is generated from a surface 20 of the polarized electron beam source 18 which is exposed to the external from the housing 22. The housing 22 is formed to be detachably installed on a vacuum chamber 24 to guide the polarized electron beam to a sample of magnetic substance in a magnetic domain observation device or the like, thereby magnetic domain observation, etc., can be performed using the polarized electron beam generated from the surface 20 of the polarized electron beam source 18 in the vacuum chamber 24.</p> |
