Abstract

A large variety of plasma conditions has been created in the tokamak à configuration variable (TCV). They include elongations in the range 1 to 2.58, triangularities between -0.7 and 1 as well as square shapes and plasma currents in the range 0.1 MA to 1 MA. Over the entire range of stationary ohmic conditions investigated a remarkable correlation has been observed between electron pressure profiles and conductivity profiles as determined by multi-channel Thomson scattering measurements. The observation implies a coupling of energy and particle transport and is at least qualitatively consistent with theoretical considerations based on minimum energy states of the plasma or on stationary entropy.
