PURPOSE:To increase the rising steepness or the discharge current and obtain strong X-ray emission by laminating a bank of capacitors, with multiple ceramic capacitors sandwiched by parallel conductor plates and flat faces of the conductor plates aligned in the nearly vertical direction to the ground. CONSTITUTION:Ceramic capacitors 20 are sandwiched between low-voltage conductor plates 21 and high-voltage conductor plates 22. After the ceramic capacitor 20 is charged, if a discharge switch 4 is turned on, charges of the ceramic capacitor 20 are quickly discharged between electrodes 11, 12. This circuit serves as a distributed constant circuit at this time, charges of the ceramic capacitor 20a at the position with the shortest electric path to a discharge tube reach between the electrodes 11, 12 first, and charges of ceramic capacitors 20b, 20c...20h flow in sequence after the fixed delay time. Since the electric path is practically shortened, the discharge current wave-form with a short rising time is obtained. As a result, the magnetic force necessary to pinch the plasma between the electrodes 11, 12 is strong, the heating temperature is increased, thus a strong X-ray output can be obtained. |
