Intense XUV attosecond physics

The research conducted at the Intense XUV Beamline at the Lund University focuses on the investigation of charge migration in different atomic gases and molecules. In order to resolve processes such as ionization or excitation, experiments require a time resolution in the attosecond range. We generate intense attosecond pulse trains in the extreme ultraviolet (XUV) using high-order harmonic generation (HHG) in gases. XUV-IR pump/probe interferometry in different target gases leads to photoelectron (PE) emission which can be strongly angle-dependent. When performing time delay scans with an angle-resolved PE spectrometer, this property gives insight into the atomic structure. Our current goal is to generate a high XUV flux to perform non-linear XUV-XUV pump/probing.
