TY  - JOUR
AB  - We present measurements of the H-like potassium (K XIX) X-ray spectrum and its Helike (K XVIII) satellite lines, which are situated in the wavelength region between 3.34 and 3.39Å, which has been of interest for the detection of dark matter. The measurements were takenwith a high-resolution X-ray spectrometer from targets irradiated by a long-pulse (2 ns) beamfrom the Orion laser facility. We obtain experimental wavelength values of dielectronicrecombination satellite lines and show that the ratio of the Lyα lines and their dielectronicsatellite lines can be used to estimate the electron temperature, which in our case was about1.5±0.3 keV.
