摘要: The first high fidelity gyrokinetic simulations of the energy losses in transport barriers large tokamaks pursuit fusion gain are presented. These calculate turbulent with an extensive treatment relevant physical effects—fully kinetic, non-linear, electromagnetic—inclusive all major plasma species, and equilibria shape local bootstrap current for fusion-relevant cases. We find that plasmas a small normalized gyroradius lie unexpected regime enhanced can prevent projected gain. Our qualitatively consistent recent experiments on JET ITER-like wall. Interestingly very importantly, predict parameter regimes reduced quite fusion-favorable.
