A poloidal cross section is a cut of the flux surface with the plane ''φ = cst''. | A poloidal cross section is a cut of the flux surface with the plane ''φ = cst''. | ||
The result of such a cut is a closed curve, of which its circumference and area are easily determined; | The result of such a cut is a closed curve, of which its circumference and area are easily determined; an effective plasma radius can then be deduced, assuming the curve deviates only slightly from a circle. | ||
The mean plasma radius can be determined by averaging the result over the angle ''φ''. | The mean plasma radius can be determined by averaging the result over the angle ''φ''. | ||
