Measurement of electric field from plasma rotation using CVI lines, 2
- 1. National Inst. for Fusion Science, Nagoya (Japan)
Description
Ion temperature and poloidal rotation velocity profiles are measured with 68 channel space resolved spectrometer using beam emission spectroscopy technique in CHS. The electric field profiles derived from poloidal rotation velocity has a large shear near the plasma edge and the absolute value of this edge electric field increases from -70 V/cm to -110 V/cm as the ion collisionality ν*i is increased from 2 to 20. The values of radial electric field measured in CHS is larger than the neoclassical estimates especially near the plasma periphery at r/a > 0.7. (author)
