Abstract: An X-ray tube structure based on a carbon nano tube is provided to improve a radio graph by using two focusing electrodes to which a different voltage is applied to minimize the variation of a focal point size. A cathode(1) is an emission source and made of a carbon nano tube. A gate unit(2) induces the emission of electrons in the carbon tube. First and second focusing electrodes(10a,10b) induce the focusing of the emitted electrons. An anode(3) accelerates the emitted electrons and generates X-ray by collision of the accelerated electrons. The first focusing electrode receives an applied voltage identical to that of the gate unit to maintain a focal point near an anode surface, similarly when one focusing electrode is used. Otherwise, the voltage applied to the second focusing electrode is controlled to minimize the variation of a focal point size regardless of the voltage variation of the gate unit.
