"Snowflake" H Mode in a Tokamak Plasma

Olivier Sauter, Basil Duval, Stefano Coda, Jean-Marc Moret, Benoît Labit, Francesco Piras, János Márki, Andreas Pitzschke

An edge-localized mode (ELM) H-mode regime, supported by electron cyclotron heating, has been successfully established in a snowflake (second-order null) divertor configuration for the first time in the TCV tokamak. This regime exhibits 2 to 3 times lowe ...
