Kraus, D.; Bachmann, B.; Barbrel, B.; Falcone, R. W.; Fletcher, L. B.; Frydrych, S.; Gamboa, E. J.; Gauthier, M.; Gericke, D. O.; Glenzer, S. H.; Göde, S.; Granados, E.; Hartley, N. J.; Helfrich, J.; Lee, H. J.; Ravasio, A.; Nagler, B.; Schumaker, W.; Vorberger, J.; Döppner, T.

We discuss the possibility of obtaining highly precise measurements of the ionization potential depression in dense plasmas with spectrally resolved X-ray scattering, while simultaneously determining the electron temperature and the free electron density. A proof-of-principle experiment at the Linac Coherent Light Source, probing isochorically heated carbon samples, demonstrates the capabilities of this method and motivates future experiments at X-ray free electron laser facilities.
