Transverse and longitudinal phase volumes are evaluated and dilution factors defined. A new and simpler expression for the effect of third-order geometric aberrations is given. Constraints on the final quadrupole bore radius are discussed. Parameters of the example design are given and the preceding analysis is applied to it. The available dilution factor allows a comparison between the present induction linac example design and the rf linac designs available in 1978. The last sections contain a discussion of phase-space limitation on attaining high power density for spot heating experiments, and a brief discussion and summary
