Abstract
In an X-ray generator device a target member emitting X-rays by electron bombardment is arranged in a rod-shaped tubular probe and is provided with a conically tapering front part facing a comparatively narrow aperture in a controlling electron beam diaphragm for the purpose of forming a substantially punctiform radiation source. The position of the target member is adjusted by securing the rod-shaped target member at a part of its length reckoned from its opposite, rearmost end in a central bore of an oblong cylindrical target carrier positioned coaxially in the probe, said target carrier being only at its foremost end connected with the wall of the probe, thereby allowing fine adjustment of the target member with respect to said aperture by displacement of said opposite end of the target carrier in a radial plane in the probe, e.g. by means of wedge means formed as adjusting screws in the annular channel between the target carrier and the inner wall of the probe.
