Difference between a tokamak and a spherical tokamak

  1. Apr 16, 2017 #1
    The title question is quite self-explanatory. Despite the fact that Spherical tokamaks are more spherical in shape, what else differentiates the ST from the conventional tokamak. I've heard that ST's use reverse field configurations from a website but I am skeptical about this since the rest suggest otherwise. Do ST' use reverse field configurations? And any other differences?

    Thanks

    The only difference is “aspect ratio”, the ratio of major radius to minor radio of the tokamak plasma. As the aspect ratio decreases, the plasma shape becomes less doughnut-like and more spherical-like, especially when the plasma has vertical elongation. When the aspect ratio is about 2.0 or below, the tokamak is arbitrarily called a “spherical torus” or "spherical tokamak."

    There is NO reverse field or any other non-tokamak feature.

    Oh. I think the reverse field thing is a part of the spheromak not the spherical tokamak . Got it. Thanks
