The very high photon densities that will be achieved with EBS will in many experiments modify the sample or its environment in a way that will affect the collected data. Such effects include structural modifications, bond breaking, photopolymerization, transport phenomena, redox processes, heating, change of macroscopic properties (e.g. electrical conductivity) or external conditions (e.g. ionization of surrounding gas molecules, …). The aim of this workshop is to make the entire ESRF user community aware of these problems by emphasizing all aspects of such sample alteration that may in some cases actually be desired. Assessment of beam damage, determination of acceptable doses, plausible mechanisms as well as mitigating strategies will be discussed.


Registration fee

Registration fee: 100€
Workshop dinner: 40€
