Quantitative analysis of the space charge force compensation by means of RF quadrupoles in a synchrotron is given. For a bunched beam, if the RF quadrupoles operating at the fundamental RF frequency (or at most the fundamental and second harmonic frequency) are applied, the linear betatron tune shift ..delta nu.., excited by the linear part of space charge force, would be diminished effectively for most particles in either a parabolic or Gaussian distribution in the longitudinal direction. Then the space charge limit of a synchrotron, mainly decided by the nonlinear tune shift, would be raised to about twice that given by the Laslett formula.
