A key requirement for the correct interpretation of high-resolution X-ray spectra is that transition energies are known with high accuracy and precision. We investigate the K-shell features of Ne , CO 2 , and SF 6 gases, by measuring their photo ion-yield spectra at the BESSY II synchrotron facility simultaneously with the 1s- p fluorescence emission of He-like ions produced in the Polar-X EBIT. Accurate calculations of transitions in these ions provide the basis of the calibration. While the CO 2 result agrees well
