Toroidal and slab ETG instability dominance in the linear spectrum of JET-ILW pedestals

Jason F. Parisi, Felix I. Parra, Colin M. Roach +9

Local linear gyrokinetic simulations show that electron temperature gradient (ETG) instabilities are the fastest growing modes for $k_y{\rho }_i\gtrsim 0.1$ in the steep gradient regio…
