摘要

This paper presents a detailed formulation and analysis of the rate equations for statistically-averaged quantities for an intense nonneutral beam propagating through a periodic solenoidal focusing field B(sup sol)(x). The analysis is based on the nonlinear Vlasov-Maxwell equations in the electrostatic approximation, assuming a thin beam with characteristic beam radius r(sub b) (much-lt) S. The results are applied to investigate the nonlinear evolution of the generalized entropy, mean canonical angular momentum (l-angle)P(sub (theta))(r-angle), center-of-mass motion for (l-angle)X(r-angle) and (l-angle)Y(r-angle), mean kinetic energy (1/2) (l-angle)X(sup (prime)2) + Y(sup (prime)2)(r-angle), mean-square beam radius (l-angle)X(sup 2) + Y(sup 2) (r-angle), and coupled rate equations for the unnormalized transverse emittance (epsilon)(s) and root-mean-square beam radius R(sub b)(s) = (l-angle)X(sup 2) + Y(sup 2)(r-angle)(sup 1/2). Global energy balance is discussed, and the coupled rate equations for (epsilon)(s) and R(sub b)(s) are examined for the class of axisymmetric beam distributions F(sub b).
