| Description: | Both analytic and numerical results indicate an increase in ETG turbulence levels as the magnetic shear is increased. Analytic growth rate calculations show ITG growth rates decreasing with increasing shear. Analytic TEM growth rates appear to be insensitive to the magnetic shear. By varying the shear and keeping the other important drive parameters roughly constant (the difficult part!) we will determine if these predictions hold up. Compare results to theory and simulation (e.g. GYRO, GS2, ..). | ||
