FIELD: acceleration equipment, acceleration of electrons by eddy electrical field. SUBSTANCE: D C power supply source is connected in parallel to excitation winding via choke and capacitor if excitation and compensation windings connected in series opposition operate while magnetic circuit is closed and capacitor is connected via thyristor to compensation winding and diode shunted additionally by diode. It is proposed to form air gap in closed magnetic circuit compensating for effect of non-linearity of steel magnetization curve to diminish change of radius of equilibrium orbit. EFFECT: increased acceleration pulse recurrence rate. 2 cl, 4 dwg
