FIELD: acceleration engineering; generation of high-energy electron beams.
SUBSTANCE: switch-mode power system of small-size betatron affording correction of equilibrium orbit radius by end of acceleration cycle has storage capacitor 4 connected through circuits of thyristors 5 and 6 built around current inverter circuit to windings 2 and 3 interconnected in series opposition, diode 7 being inserted in circuit of compensating winding 3. Connected in parallel with winding 2 through switching choke 9 and capacitor 10 is dc-to-dc converter 8. Capacitor 10 is connected through thyristor 11 and diode 7 to winding 3, winding 3 and diode 7 being shorted out by diode 12. Correction circuit choke 13 and thyristor 14 are connected in parallel with thyristor 11. Converter 8 is connected through variable resistor 15 to one plate of correcting capacitor 16. The latter is connected in parallel with winding 3 and diode 7 through correction circuit thyristor 17 and resistor 18.
EFFECT: reduced size and mass, enhanced reliability of proposed power system.
