For effective implementation of modern methods of X-raying required equipment complexes with increased requirements to the generator X-rays compared to conventional devices used in radiography. These requirements basically boil down to the fact that the radiation source along with small dimensions should provide at least 0.5 m from the target minimum exposure dose of about 10 mR for 1 with the appliance with a minimum area of the radiating surface of the target. These parameters are obtained by using X-rays generator based on high-current diode accelerating tube (AT) operating in the pulse-periodic regime at current amplitude of the accelerated electrons in the tube Im ~ 1 kA, pulse duration 1-10 ns and a maximum energy of electrons reaching several hundred keV The report presents the development of compact AT, which improved definition x-ray image is ensured by using a diode system with a coaxial geometry acceleration of electrons to the anode electrode internal target and explosive emission cathode. AT used to run a specially designed high-voltage pulse transformer-based "Tesla" with surge sharpener. Describes the design and block diagram interface generator X-ray quanta. Feature is the high stability of the generator is not dependent on the voltage, battery charge. Presented the results of experimental testing of the generator X-ray quanta. Also shows the waveform duration x-ray pulses in the presence of the lead filter and without it.
