Abstract :
The advanced active-current control with a push-up voltage source is proposed to operate a carbon nanotube (CNT) field-emission X-ray tube rapidly with maintaining the advantages of improved stability and reliability. The push-up voltage source, comprising of a resistor and a voltage supply, strongly reduced the response time of CNT X-ray tubes down to several μs.
