On 3 September representatives from LEAPS members took part in a hybrid session at ESOF2020.
The session focused on the contribution of accelerator-based photon sources on three important subjects: (i) the new regime of X-ray matter interactions with ultrashort very intense X-ray pulses, (ii) the new potential of coherent imaging and scattering for answering questions about nano dynamics in complex materials and (iii) the unique possibility to stimulate and probe nonlinear phenomena that are at the heart of conversion of light into other forms of energy, relevant to photovoltaics, magnetism and phase transitions in correlated materials.
