Abstract

The cold cathode x-ray source was fabricated by using the point-type CNT film emitter. The CNT x-ray source consists of the CNT point emitter, the metal mesh gate electrode and the tungsten target anode electrode. Those components were mounted in a small vacuum chamber. The fabricated CNT x-ray source shows a high resolution x-ray image at a low anode current and at a low anode voltage compared to conventional thermionic x-ray sources. The achieved high performance of the cold cathode x-ray source is caused by high density electron beam emitted from the point-type CNT film emitter. Our results indicated that the point-type CNT film emitter is very useful for the CNT based cold cathode x-ray sources.
