The low of formation of accelerating voltage frequency change in the IHEP ring booster injector

Block-diagram of a new section for accelerating field frequency formation in the ring injector - the IHEP booster is described. To obtain the effective tuning range of 0.7-2.8 MHz, heterodyne method with two controlled oscillators was used. Two oscillators are connected in the same circuit, their circuits have similar inductance coils and are placed into an aggregate thermostat. Block-diagrams of a master oscillator, an initial frequency oscillator and a function converter are given. Digital control application permitted not only to improve main section characteristics but to gain new possibilities for using computers. Control program provides work with equipment, dialogue with an operator, and a specialized operational system provides regime rescuing and restoration
