| Research Abstract |
The plasma X-ray generator employs a high-voltage power supply, a low impedance coaxial transmission line, a high-voltage power supply, a low impedance coaxial transmission line, a high-voltage condenser with a capacity of 400nF, a turbo-molecular pump, thyrister pulse generator as a trigger device, and a flash x-ray tube. The high-voltage main condenser is charged up to 80 kV by the power supply, and the electric charges in the condenser are discharged to the tube after triggering the cathode electrode. The flush x-ray are then produced. As the electron flows from the cathode electrode are roughly converged to the cerium target by the electric field in the peak tube voltage was almost equal to the initial charging voltage was increased, the linear plasma x-ray source formed and the characteristic x-ray intensities of K-series line increased. The quasi-monochromatic radiography was performed by a new film-less computed radiography system.
