Abstract
We fabricated the cold cathode X-ray source composed of point-type CNT field emitter, mesh gate electrode, e-beam focusing lens and W anode. The point-type CNT field emitter was made by CNT film with a triangular tip shape. Field emission properties measured in triode configuration showed the low turn-on and threshold electric fields, the high emission current and focused electron beam spot. The CNT field emitter based cold cathode X-ray source reveals high resolution X-ray images. We demonstrated that the point-type CNT emitter is suitable candidate for the high performance cold cathode X-ray sources.
