FIELD: acceleration engineering; generation of high-energy electron beams. SUBSTANCE: twin betatron power system has its storage capacitor connected through thyristor to field coil of first electromagnet and field coil of second electromagnet connected through other thyristor to storage capacitor. Connected in parallel with field coil of first electromagnet is first power input circuit set up of series interconnected dc power supply, choke coil, and additional thyristor. Connected in parallel with field coil of second electromagnet is second power input circuit set up of series-interconnected dc power supply, choke coil, and thyristor. EFFECT: reduces cost, mass, and size of twin betatron. 1 cl, 3 dwg
