Abstract
A 30 kHz pulsed x-ray generator utilizing a hot-cathode triode in conjunction with a new type of grid controller for varying the x-ray duration is described. This generator consisted of the following essential components: a constant high-voltage power supply, a high- voltage main condenser of 97 nF, a DC power supply for the filament (hot cathode), and a hot-cathode triode. The high-voltage main condenser was charged from 50 to 70 kV by the power supply, and the electric charges in the condenser were discharged to the x-ray tube repetitively by the grid controller. The maximum values of the grid voltage (negative value) and the tube current were about -2.2 kV and 0.6 A, respectively. The x-ray duration was controlled by the time constant of the grid controller and the electron cutoff voltage. The x-ray intensity with a pulse width of 70 microsecond(s) and a charged voltage of 70 kV had a value of 1.26 (mu) C kg-1) at 0.5 m per pulse. The maximum repetition rate was about 30 kHz, and the size of the x-ray source had a value of 3.5 X 3.5 mm.
