Edge Radial Electric Field in Positive and Negative Triangularity Plasmas in the TCV Tokamak
Abstract
We present the first edge Er measurements in negative triangularity (NT) TCV plasmas. The Doppler backscattering measurements of v ≈ Er/B reveal a significant impact of triangularity on the Er well: In Ohmic, NBI, and ECRH heated discharges, the Er well and associated Er × B shear are stronger in NT-shaped plasmas compared to their positive triangularity (PT) counterpart. This suggests a connection to the concomitant NT performance gain relative to PT L-mode.
