A multi-machine database for the H-mode scrape-off layer power fall-off length, λ q in JET,
DIII-D, ASDEX Upgrade, C-Mod, NSTX and MAST has been assembled under the auspices …

Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads
to tolerable heat and particle loads on the wall is a major challenge. The new European …

Magnetic-fusion plasmas are complex self-organized systems with an extremely wide range
of spatial and temporal scales, from the electron-orbit scales (∼ 10− 11 s,∼ 10− 5 m) to the …

Edge-localized-modes (ELMs) are a ubiquitous feature of H-mode in tokamaks. When
gradients in the H-mode transport barrier grow to exceed the MHD stability limit the ELM …

A future fusion reactor is expected to have all-metal plasma facing materials (PFMs) to
ensure low erosion rates, low tritium retention and stability against high neutron fluences. As …

Progress in the definition of the requirements for edge localized mode (ELM) control and the
application of ELM control methods both for high fusion performance DT operation and non …

A heuristic model for the plasma scrape-off width in low-gas-puff tokamak H-mode plasmas
is introduced. Grad B and curv B drifts into the scrape-off layer (SOL) are balanced against …

High-performance and long-pulse operation is a crucial goal of current magnetic fusion
research. Here, we demonstrate a high-confinement plasma regime known as an H-mode …

Detachment of high power discharges is obtained in ASDEX Upgrade by simultaneous
feedback control of core radiation and divertor radiation or thermoelectric currents by the …

The physics base for the ITER Physics Design Guidelines is reviewed in view of application
to DEMO and areas are pointed out in which improvement is needed to arrive at a consistent …
