Abstract: The internship will make it possible to adapt the process of flash photolysis of H2O2 to its measurement in operando under ionizing radiation. For the proof of concept, it will be necessary to determine the best chemical system and the protocol to analyze the concentration of H2O2 formed during the radiolysis of water with heavy ions.

Abstract: The objective of the internship is to modify and optimize the properties of a femtosecond laser in order to extend the laboratory's experimental capabilities on the study of attosecond (1 attosecond = 10^-18 second) dynamics during laser-matter interaction, and in particular the fundamental mechanisms of the generation of high order harmonics in semiconductor crystals.
