ITER reached 50% completion of the work required to achieve First Plasma in November
2017. Progress has been made on ITER infrastructure since the 2016 Fusion Energy …

Recent measurements of the Ly β/D α ratio in the JET ITER-like wall (ILW) divertor show
comparatively more pronounced Ly β reabsorption relative to previous results in JET with …

The study aims to estimate the influence of machine scale size on the behavior of plasma
with extrinsic seeded impurities in the scrape-off layer (SOL) and divertor. This is performed …

In the four-stage approach of the new ITER Research Plan, the first pre-fusion power
operation (PFPO) phase will only have limited power available from external heating and …

Numerical access to cold divertor conditions in tokamaks with EMC3-EIRENE has been
proven to be challenging, but is now possible for the first time after a linearization of the …

A qualitative picture of development of a bifurcated plasma state in a single-null and double-
null divertor configurations is discussed. The simple analytical considerations are verified …

Until recently the EIRENE suite handled hydrogen chemistry (ie H atoms, H 2 molecules,
and H 2+ molecular ions and their isotopomers). Extensions also exist for hydrocarbon …

Good plasma performance in magnetic fusion devices of different types, both tokamaks and
helical devices, is achieved normally if the plasma density does not exceed a certain limit. In …

Plasma-facing materials in future large-scale fusion reactors must be designed to withstand
high heat fluxes from extreme off-normal events such as edge localized modes and …
