  1. Study of the poloiadal rotation in RF heating plasma Proposal for HT-7 in 2008 Experimental Campaign Presented by Yuejiang Shi

  2. Purpose • Study the poloidal rotation in RF heating plasma. The poloidal rotation shear in IBW heating plasma has been observed in TFTR and is considered as the main mechanism for the improved confinement . • In the last HT-7 experimental campaign, the poloidal rotation in IBW plasma has been observed. But the S/N is not so good. We hope to get more better signal in this experimental campaign.

  3. Study the poloidal rotation in RF heating plasma TFTR: Experimental carbon v at six major radius locations during (a) discharge with IBW power; (b) discharge without IBW power.

  4. The poloidal rotation velocity measured with CXRS………………………….

  5. Experimental parameters Normal operation with IBW and LHCD Fixed parameters: Ip~150kA Scan paramters: Bt: 1.7T, 1.8T, 1.9T Fibw: 27MHz, 30MHz Nel: 1.5, 2.0, 2.5 Pibw: 50, 100, 200, 300, 400 Plhcd: 200,500
