Abstract

Significant ion toroidal rotation ( 50km/s) has been measured by X‐Ray spectroscopy for impurities in Alcator C‐Mod during lower hybrid (LH) RF power injection [1]. We investigate the relation between the computed toroidal momentum input from LH waves and the measured INITIAL change of ion toroidal rotation when the LH power is turned on. The relation may depend on the plasma current and magnetic configuration [2, 3]. Because of the fast build up time of the electron quasilinear plateau (
