FIELD: acceleration engineering; generation of high-energy electron beams. ^ SUBSTANCE: system has storage capacitor 4 connected through arms of thyristors 5 and 6 using current inverter circuit arrangement to windings 2 and 3 interconnected in series opposition, diode 7 being inserted in circuit of compensating winding 3. Power supply 8 is connected in parallel with field winding 2 through switching reactor 9 and capacitor 10. The latter is connected through thyristor 11 to diode 7 and winding 3, both being shorted out by diode 12. One plate of correcting capacitor 13 is connected through resistor 14 to common point of field winding 2, compensating winding 3, and low-voltage power supply 15; the latter is connected through reactor 16 to common point of winding 2 and switching reactor 9. Other plate of capacitor 13 is connected through correction-circuit thyristor 17 to common point of diodes 7 and 12. High-voltage dc power supply 18 is connected in parallel with capacitor 13 and variable resistor 19. Thyristor 20 is connected in parallel with reactor 9 and field winding 2. Proposed betatron power supply system ensures stabilization and regulation of accelerated electron kinetic energy due to parallel connection of thyristor 20 to field winding 2 and switching reactor 9. Connection of correction-circuit thyristor 17 to common point of diodes 2 and 7 makes it possible to reduce reverse voltage across this thyristor by value of no-load voltage across compensating winding 3 thereby reducing cost of equilibrium orbit radius correction circuit. ^ EFFECT: enhanced reliability of stabilizing and regulating kinetic energy of accelerated electrons. ^ 1 cl, 4 dwg |
