Investigation of Toroidal Acceleration and Potential Acceleration Forces in EAST and J-TEXT Plasmas

Experiments were performed on EAST and J-TEXT for ohmic plasmas with net counter- and co-current toroidal acceleration generated by density ramping-up and ramping-down. Core toroidal rotation is increasing with Te/Ti increasing in observed region (r /a ≤ 0.3). There may be certain correlation betwee...
