摘要：

The nonlinear space charge effect of bunched beam in linac is one of the important reasons that induce the emittance growth The general formulas for calculating the potential of space charge with nonuniform distribution in surrounding structure are presented. For a bunched beam with different distribution in waveguide of linac, the expresses of the nonlinear field energy of a cylinder model of space charge are derived, and the numerical results of the nonlinear field energy for different density distributions are given. The emittance growthes caused by these nonuniformities are discussed.
