Abstract
A method for generating an X-ray includes the steps of: disposing at least a target in a chamber; irradiating an electron beam onto the target from an electron beam source disposed in or outside the chamber so as to satisfy a relation of β≦60 degrees if an incident angle of the electron beam is defined as 'β'; and generating and taking an X-ray out of the target so as to satisfy a relation of −30 degrees≦β−α≦60 degrees if an output angle of the X-ray relative to a surface of the target is defined as 'α'.
