Flows in the Textor Sol and Edge Plasma

Poloidal asymmetries in the electron density profiles and limiter diagnostics suggest that poloidal and toroidal flows exist in the SOL and edge plasma of the TEXTOR tokamak. A fast reciprocating probe located at the outer midplane provides profiles of the basic plasma parameters including radial electric field and fluctuation driven transport. Based on the probe measurements, we calculate the E(r) X B(t) drift velocities and phase velocities of the turbulence. The measurements are compared to each other. The above measurements are compared to calculations using the SOLXY code for B(t) and I(p) in normal and inverted configuration.
