Abstract
The present invention relates to a device for generating X-rays by means of an accelerated electron beam created by the potential difference between an X-ray target and surface charges induced on both end surfaces of a pyroelectric crystal by irradiating radiant heat onto the crystal. A high-energy electron beam is generated by inducing a temperature change in a pyroelectric crystal through the irradiation of radiant heat, thereby minimising temperature deviation in the diametral direction and the length direction of both end surfaces of the pyroelectric crystals, thereby overcoming the size limitations and the structural limitations of pyroelectric crystals used in the prior art and increasing the potential difference which results from increasing the number of induced surface charges. The performance of X-ray generator devices is improved by using the electron beam.
