Comparison of scrape-off layer transport in inner and outer wall limited JET plasmas
Carlos A. Silva,G. Arnoux,Stéphane Devaux,D. Frigione,M. Groth,J. Horacek,P.J. Lomas,S. Marsen,G.F. Matthews,R. A. Pitts,Jet-Efda Contributors +10 more
TL;DR: In this paper, the JET scrape-off layer has been characterized with a reciprocating probe in inner wall, IW, and outer wall, OW, limited plasmas, and the striking differences observed between IW and OW limited Plasmas on the power e-folding length, parallel flow, turbulent transport as well as the characteristics of the fluctuations support the existence of a poloidally localized region of enhanced radial transport near the outboard midplane.
