---------------------------------------------------------------------------------------------- Project: A12 Title: Multi-particle analysis of ultrafast molecular photoreactions DESY group: FS-ATTO (Attosecond Science) Type: Remote project Duration: 19th july - 10th sep 2021 Description: In the attosecond science and technology group at CFEL (https://atto.cfel.de), we generate ultrashort laser pulses with attosecond (1 fs = 10^−18 s) or few-femtosecond (1 fs = 10^−15 s) duration. We use them to trigger photoreactions in molecules (often biologically relevant ones) and to follow in real-time how the atoms and electrons move and interact. With our research we aim at understanding and potentially manipulating ultrafast processes and, ultimately, the early steps of photochemistry. We can host up to two students, who will learn (via online meetings) about experimental methods in ultrafast laser and molecular science, as well as the scientific motivations and challenges driving this research field. After training, the students will write programs/scripts to analyse existing experimental data and discus with us to refine the conclusions and follow up ideas. This includes combined photoion & photoelectron data that give information about ultrafast dynamics in molecules from experiments with infrared, ultraviolet and/or extreme ultraviolet photons. We are currently building a soft x-ray beamline and hope to be able to let the students follow this process and analyse the first spectra. Special Qualifications expected: Programming experience helpful, but not required Link to further information: https://www.desy.de/f/students/2021/projects/A12.pdf ----------------------------------------------------------------------------------------------
