説明
The diagnostic soft flash x-ray generators and their applications to high-speed radiography are described. Each flash x-ray generator consisted of the following essential components: a high-voltage power supply, a high-voltage pulser, a high-speed impulse switching system, and an x-ray tube. The flash x-ray generators may be used for peak tube voltages of 40 to 150kV and the peak currents of less than 5OkA. The exposure times were less than 50μs, and the x-ray qualities were primarily determined by the peak voltages of the x-ray tube. The repetitive rate was determined by the capacity of the main discharge condenser, the charged voltage, and the current capacity of the high-voltage power supply; its value was less than 50Hz. But, when a flash x-ray generator with an energy storage condenser was employed, the repetitive rate can be increased up to 100Hz. Various kinds of high-speed radiography, e. g., the delayed radiography and the stroboscopic radiography, could be performed by controlling the following radiographic conditions: the x-ray intensity, the x-ray quality, the exposure time, the delay time, and the repetitive rate.
