Investigation of Long Wavelength ETG Modes

POSTER

Abstract

Simulations of ETG turbulence suggest that the greatest energy transfer is through long wavelength modes ($k_\theta \rho < .1$) The effect of curvature as a cutoff on long perpendicular wavelength electron turbulence is investigated. Analytic calculations are presented along with simulations from the gyrokinetic code GYRO.
