THE PEAK TOROIDAL FLUX DENSITY REQUIRED AT VARIOUS STAGES IN THE PROGRAMME OF TOKAMAK DEVELOPMENT
The incentives, risks and benefits associated with the development of high toroidal field coil systems to satisfy the aims of various devices in the tokamak development programme are investigated. An assessment is made by examining the parameter space available to devices with specific programme aims by using a simple model relating physical and technological parameters with cost. The results are sensitive to both physics and engineering assumptions, but insensitive to the scaling of magnet costs themselves with field. The most critical parameter determining the need for flux densities at or beyond 12 T is the blanket and shield thickness needed for adequate tritium breeding and efficient electricity generation.
