High-frequency accelerating field amplitude programmer for electron synchrotron

A system for forming the amplitude modulation of the high-frequency accelerating voltage of an electronic synchrotron based on information about the guiding magnetic field of the synchrotron is described. The circuit permits regulating the scale factors of the hf voltage modulation independently of one another which makes it possible to modulate the hf voltage amplitude over a wide range. The system employs analog functional units which enable automatic formation of the required modulation law when the accelerator is tuned from one energy to another. The modulation law is set with a relative accuracy of plus or minus 1%.
