ABSTRACT:
An X-ray source provides for selective variations of the wavelength spectra or other characteristics of the X-ray output by including means for directing an electron beam to any selected one of a plurality of target-anodes. Beam energy may also be selectively adjusted. Beam position stabilization means respond to any change of beam energy by making compensating changes in the deflection signals so that the electron beam remains directed at a selected point on a selected target-anode in the presence of energy changes including both deliberate energy changes and variations resulting from random voltage fluctuations in the beam accelerating system. The beam position stabilization means may include a function generator to accommodate to a non-linear relationship between beam energy changes and the deflection signal changes required to maintain a selected beam trajectory.
