TL;DR: In this paper, three options of fusion DEMO plant are proposed characterized by functions of the center solenoid (CS), and the prime option uses a downsized CS, which does not provide sufficient V-s for plasma current ramp-up but supplies enough coil current for plasma shaping.

TL;DR: In this article, measurements of the SOL flow and plasma profiles both at the high-field-side (HFS) and low-field side (LFS), for the first time, identified the sol flow pattern and its driving mechanism.

TL;DR: The plasma profile and parallel plasma flow in the scrape-off layer (SOL) were systematically measured using reciprocating Mach probes installed at the outer midplane and near the divertor magnetic null in the JT-60U tokamak with a single null divertor.

TL;DR: In this paper, the divertor geometry was compared in the open and W-shaped divertor and the ion flux near the outer strike point was larger than the open divertor, and the electron temperature at the target was reduced.

TL;DR: In this article, the effect of the connection length on the decay lengths of ne,mid, temperature Te,mid and ion temperature Ti,mid in the scrape-off layer (SOL) was investigated under radiative and detached divertor conditions in L-mode discharges.
