General principles of magnetic confinement

This chapter examines basic magnetic confinement issues such as single particle confinement, finite pressure equilibrium and stability, and transport. Describes the major approaches to magnetic confinement; tandem (ambipolar) mirrors with their associated auxiliary barriers, tokamaks and stellarators; and EBT and Reversed Field Pinch as the leading alternatives. Discusses the evolution equations for particle, energy and, where relevant, field diffusion. Offers a case study of H /SUP o/ charge exchange with multiply charged ions. Presents a tandem mirror configuration with neutral injection to sustain the end cell density, solenoid and yin-yang coils. Points out that equilibrium and stability considerations provide the bases for transport timescale analysis
