Abstract

The high performance cold cathode X-ray source was fabricated by using the point-typed CNT field emitter. The cold cathode X-ray source consists of the CNT point emitter, the metal mesh gate electrode, the metal hole focusing lens and the tungsten target anode electrode. To fabricate X-ray source, such components were mounted in a SUS vacuum chamber. The fabricated CNT X-ray source showed a good resolution of X-ray images at a low anode current and at a low anode voltage, and also indicated stable operation. We evaluated X-ray images according to the tube voltage and the tube current, respectively.
