In recent automated design studies, optimal design methods were introduced to successfully reduce the often excessive heat loads that threaten the divertor target surface. To this end, divertor coils were controlled to improve the magnetic configuration. The divertor performance was then evaluated using a plasma edge transport code and a...

Our global understanding of the power exhaust in tokamaks, and its implications for both steady-state and transient heat loads on divertor and limiter PFCs, is still poor. In transient situations in particular, such as during start-up or control operations, the evolution of particles and heat fluxes is little known, although being critical for...

The ballooned nature of cross-field transport is shown to govern the steady state divertor imbalance of the energy flux leading to a factor 10 between the low field side and high field energy flux. An even stronger ratio is found for the divertor temperatures. Conversely the particle flux is expected to be a factor 10 larger on the high field...
