Impurities and sawteeth
Criteria for maximum tolerable concentrations of impurity ions within the hot core of a fusion plasma are derived from power balance considerations. The dominant processes for impurity production as well as appropriate countermeasures are outlined. A phenomenological description of sawtooth activity is provided and the detrimental effect of periodic confinement degradations in a burning fusion plasma is reported. Technical means of suppressing sawteeth are indicated.
