Gyrokinetic Simulations of Enhanced Alpha Transport by De-stabilized Alfv\`en Turbulence*

Alfv\`en turbulence, destabilized by fusion-produced $\alpha$-particles, is expected to greatly enhance transport of these hot fusion products. Previously, the gyrokinetic code GYRO [1] was used to simulate the convective transport of fusion alpha particles by electrostatic ($\beta=0$) ITG/TEM turbulence driven at low $k$ ($0
