We present in situ measurements of spectrally resolved X-ray scattering and X-ray diffraction from monocrystalline diamond samples heated with an intense pulse of heavy ions.In this way,we determine the samples'heating dynamics and their microscopic and macroscopic structural integrity over a timespan of several microseconds.Connecting the ratio of elastic to inelastic scattering with state-of-the-art density functional theory molecular dynamics simulations allows the inference of average temperatures around 1300 K,in agreement with predictions from stopping power calculations.The simultaneous diffraction measurements show no hints of any volumetric graphitization of the material,but do indicate the onset of fracture in the diamond sample.Our experiments pave the way for future studies at the Facility for Antiproton and Ion Research,where a substantially increased intensity of the heavy ion beam will be available.
