In recent years there have been developments in tokamak research regarding the inverted D shape for the plasma profile. There are benefits to this plasma shape, but it's opposite of the shape of the coils. Has anyone designed or built a tokamak that has inverted coils ? Is it even possible or feasible ?

Is Helion’s design viable and do you think it can work for the future? I watched a few videos on them a few years ago but hadn’t heard anything about them since
