The dynamics of the diffraction peak shape during pulsed heat load on mosaic single‐crystal tungsten were measured at the `Plasma' scattering station on the eighth beamline of the VEPP‐4 synchrotron radiation source at the Budker Institute of Nuclear Physics. The observed evolution of the diffraction peak shape agrees with theoretical predictions based on calculations of deformation caused by pulsed heating. Three clearly distinguishable stages of the diffraction‐peak evolution were found, correlating with the evolution of temperature and deformation distributions. The residual plastic deformation increased with subsequent heating pulses.
