摘要

研制成功了一种具有碳纳米管发射体的大聚焦x射线管。当铜栅栅电压为2.7kV时，阳极电流为1.15mA。x射线焦斑尺寸非常小，小于39μm，可以获得非常高的特殊分辨率x射线图像。

Microfocus X-ray tube based on CNT array

A macro-focus X-ray tube with CNT emitters was successfully developed. An anode current of 1.15mA was collected when the copper grid gate voltage was 2.7kV. A very small x-ray focal spot size with less than 39μm can be achieved, which could potentially produce very high special resolution X-ray image.
