Abstract

We fabricated the point-type CNT emitter for cold cathode x-ray source applications. The CNT point emitter was made by CNT film with a triangular tip shape, which was clamped using two stainless steel plates. Electrical properties of the point-type CNT emitter measured in triode structure showed the low turn-on and threshold electric fields, the high emission current and relatively high electron transmittance. The x-ray sources made by the point-type CNT film emitter indicated good performance, which reveals high resolution x-ray images at a low anode current and at a low anode voltage. Our results indicated that the point-type CNT emitter is very useful for the high performance cold cathode x-ray sources.
