I'm going to have, I have RF going to a coil at the outside of the plasma, and what it does, it induces a toroid of plasma, so I have, let's say, three or five turns in the outside of the plasma, and I have a one-turn toroid in the center of my plasma.
But always think of it, we're inducing a single toroid of plasma in an ICP, and I'll show you how we use that to get, we can get a uniform plasma out of it, and we can control, separately, we can control the ion energy.
