摘要： An X-ray source (100) for generating X-ray radiation of first and second energy spectra is proposed, wherein the X-ray intensity imbalance between the first and second energy spectra is reduced as compared to conventional X-ray sources. The reduction of the X-ray intensity imbalance is achieved by configuring a smaller electron impact angle (141) onto the anode (102) when the higher tube voltage is applied as compared to when the lower tube voltage is applied.
