Abstract: Plasma transport is a phenomenon in which plasma particles and heat go from the plasma center to the periphery across the magnetic surface. This chapter discusses plasma transport and confinement and resulting constraints on the operation range. Plasma transport and confinement are important for maintaining the stability of fusion reaction. Experiments on magnetic confinement have shown that various instabilities exist in plasma. Scaling laws of energy confinement time have been obtained based on data of plasma experiments in the world. Various types of edge localized mode (ELM) have been observed in experiments and ELM can be classified from detailed temperature and density profile measurement and stability analysis of the edge plasma. The Greenwald density limit has been derived from the database of Joule-heating plasma. As high-energy particles, α particles are generated by the deuterium, tritium reaction. It is necessary to confine the α particles in the plasma until they are thermalized and heat plasma efficiently.
