Nonlinear beam-dynamics calculations are described that account for space-charge and image-charge effects. The calculation technique is explained and, as an illustration, is applied to two elements in an intense beam-combining funnel: an rf rebuncher

Nonlinear emittance growth produced by ion extraction is considered by a 3‐D analysis in a Vlasov–Poisson–Boltzmann formulation. Phenomena considered include (1) presheath effects, including electron depletion, (2) electron sheath accumulation

The next-generation fusion devices based on the tokamak confinement concept are expected to emphasize steady-state operation. Such future reactors may include designs like the International Thermonuclear Experimental Reactor (ITER) and that of the re

The energy loss in a torus vessel during startup is now an important factor in a power-producing tokamak design. The torus design cannot be based on a system which minimizes the conductivity with resistive structures as in present experimental device

This paper describes a computer code developed to model a tandem mirror reactor. This is the first tandem mirror reactor model to couple the highly linked physics, magnetics, and neutronic analysis into a single code. Results from this code for two s

Optimal double-T bundle divertor configurations have been obtained for the Fusion Engineering Device. On-axis ripple is minimized, while satisfying a series of engineering constraints. The ensuing nonlinear optimization problem is solved via a sequen
