Simulation technologies, which efficiently process full-f gyrokinetic simulations on Peta-scale machines, are developed, and spatio-temporal scales of plasma transport numerical experiments are significantly expanded. Mechanisms to form and sustain intrinsic plasma rotation profiles are clarified by long time numerical experiments over a confinement time. Through ITER-size numerical experiments, it is found that the power scaling of turbulent transport greatly affects confinement scalings in large devices.

仿真技术，有效地处理全f陀螺运动模拟的Peta规模的机器，开发和等离子体输运数值实验的时空尺度显着扩大。通过长时间的数值实验，阐明了形成和维持内禀等离子体旋转轮廓的机制。通过ITER尺度的数值实验，发现湍流输运的功率标度对大型器件中的约束标度有很大的影响。
