    Abstract

    The possibility of using the field generated by electrostatic quadrupole electrodes to increase the focusing force in the working chamber of a betatron is considered. It is shown that with a number of quadrupoles N ≥3 focusing in the axial direction, for an equal number of quadrupoles focusing in the radial direction at electrode voltage U ≥15 kV during injection and the initial stage of the cycle an increase in focusing force to the limits of rigid focusing is possible. Experimental testing was performed with an operating betatron. A pair of electrodes with azimuthal extent of 26° located above and below the beam being accelerated was used, with the second electrode pair formed by the conductive chamber coating. An increase in radiation intensity of 30% was achieved.
