Experimental verification of reverse order of diagnostic X-ray beam quality in voltage-ripple dependence

It has been generally expected that, as X-ray tube-voltage ripple increases, the X-ray spectrum shifts to the low photon-energy side, and therefore the mean energy decreases, i.e. the beam quality is softened....
