This makes no reference to any different result for the relativistic case,
noting only that the plasma must be neutral for the pinch effect to win. Given
time I (you, too) will look into calculational details.
My guess is that the pinch effect wins in the "awe.co diode" for reasons (of
construction) other than just relativistic velocities.
