Density Fluctuations are Reduced Substantially inside Rs
Results are in agreement with gyrokinetic simulations*: ion-scale core modes are stable due to:
- FLR effects (large ion orbits)
- short connection length/favorable grad-B
Shown here are “low-kq” fluctuation levels: kq rs ~ 2-4
Typical DBS probing radii
