Abstract

The relationship between the density of electron emitters and x-ray image quality has been investigated. Under diode mode, x-ray images have been successfully acquired even under 30kV of bias. Vertically aligned CNT emitters were grown as electron emitters. With respect to the inter-emitter pitch, even at the same electrical energy, different emitter patterns showed different image qualities. By optimizing the CNT emitter design, we expect that we can develop a high-resolution x-ray source without using additional focusing components.
