Abstract :
In this paper, we report a point X-ray emission obtained from a diode configuration composed of a graphite-nanofiber cold cathode and a conical-shaped copper metal anode. when combined with a high sensitive charge coupled device camera with a scintillator, this X-ray source was then used to obtain X-ray transmission images of an X-ray test chart. The spatial resolution of the X-ray radiography was on the order of 10 /spl mu/m.
