SOL width broadening by spreading of pedestal turbulence

Spreading the word, broadening perspectives

Globalisation is ambivalent. On the one hand, it brings prosperity, comfort and convenience in the form of economic growth, technological advancement, more open and democratic governance, and so forth. On the other hand, there are vast amounts of casualties from its progress, which only benefits some groups or countries. Non-Government Organisations (NGOs) in Indonesia have established themselv...

ITER edge database investigations of the SOL width

Based on the ITER edge database, comparisons among the major tokamaks (ASDEX, ASDEX-Up, COMPASS-D, C-MOD, DIII-D, JET, JFT-2M and JT-60U) with respect to systematic SOL-width behavior are presented in terms of free-form regression analysis for kne and kTe . Emphasis is placed on OH-L plasmas as this data is most abundant and coherent. Despite di€erences in size, wall-conditioning and divertor c...
