在JT-60 U中研究了固定β时碰撞度对基座结构的影响。在ITER相关的低碰撞制度，基座宽度不随边缘碰撞。在高碰撞区域，基座宽度随着边缘碰撞的增加而变宽。在低碰撞度下，当基座接近中间n剥离-气球模式边界时，基座压力梯度和宽度没有显著变化。实验结果表明，传统的基座模型，其中基座宽度是独立的碰撞，并决定于
The dependence of pedestal structure on collisionality at fixed beta has been investigated in JT-60U. In the ITER-relevant low collisionality regime, the pedestal width does not change with edge collisionality. In the high collisionality regime, the pedestal width broadens with increased edge collisionality. The pedestal pressure gradient and width are not significantly changed when the pedestal is close to an intermediate n peeling-ballooning mode boundary at low collisionality. The experimental result indicates that conventional pedestal models where the pedestal width is independent of collisionality and is determined by
