Theory-based scaling of the SOL width in circular limited tokamak plasmas

Gilles Arnoux, Ivo Furno, Sébastien Jolliet, Jan Horacek, Benoît Labit, Joaquim Loizu Cisquella, Paolo Ricci, Annamaria Mosetto, Federico David Halpern

A theory-based scaling for the characteristic length of a circular, limited tokamak scrape-off layer (SOL) is obtained by considering the balance between parallel losses and non-linearly saturated resistive ballooning mode turbulence driving anomalous perp ...
