Paper Abstract

We proposed a new addressing method that used a field emitter type electronic source for the radiation imaging detector. We enabled this device to operate room temperature by using Cadmium Telluride (CdTe) diode. In this addressing method, the energy of the electron from electronic source in each pixel was much uniformed and the electron beams can be focused within a micro meter diameter. Therefore, because this proposed device was lead out by field emitter, it was expected to achieve the super-high resolution X-ray imager. In this paper, we used the carbon nanoneedle field emitter, and the proposed device operation was confirmed by verifying principle about one pixel.
