Spontaneous plasma rotation in limited and diverted TCV ohmic discharges

Introduction. This paper compares measurements of intrinsic toroidal plasma rotation in the TCV tokamak for limited and diverted magnetic configurations. Toroidal rotation profile were measured in ohmically heated L-mode configurations (no external torque applied) by a Charge eXchange Recombination Spectroscopy diagnostic in a previously described experimental ar-rangement [4]. For ohmic TCV discharges with ne up to 8 × 1019 m−3 an experimental uncer
