PROJECT TITLE :

Fast and Stable Operation of Carbon Nanotube Field-Emission X-Ray Tubes Achieved Using an Advanced Active-Current Control

ABSTRACT:

The advanced active-current control (ACC) with a push-up voltage supply is proposed for the quick operation of carbon nanotube (CNT) field-emission x-ray tubes while preserving the benefits of improved stability and reliability. The push-up voltage supply, composed of a voltage offer and a resistor, was found to cut back markedly the response time of CNT x-ray tubes down to several tens nanoseconds. The very fast operation of CNT x-ray tube with the advanced ACC may offer an improved x-ray imaging technology, as well as high-speed scanning and blur-less imaging.
