By controlling the radial density profiles of the light and heavy ions, the overall coupling efficiency (equal to the summed kinetic energy of the light ions in the highest 1% energy band divided by total kinetic energy of both ions) is optimized to be >30%–40% when about 90% of the total number of light ions is contained in the thin 1% energy band.
