摘要
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 39 mu m can be achieved, which could potentially produce very high special resolution X-ray image.
