The iRTG, in collaboration with the Max Born Institute, offers a series of ATMs:
Laser-driven Resonant Soft-X-ray Scattering probing Antiferromagnetic & Structural Dynamics,
In this lab course, you will work with a tabletop setup for picosecond soft-X-ray resonant magnetic scattering experiments. For that, the broadband emission of a laser-driven plasma X-ray source from 500–1500eV is employed. You will first statically characterize the antiferromagnetic and structural Bragg peaks of on artifical AFM sample (Fe/Cr superlattice). Afterward, you will probe both, the structural and AFM dynamics, in a single pump-probe experiment. In the second (optional) part (ATM 3) of the lab course on Friday (onsite or online), you will learn how to model the static as well transient results, using the open-source Python toolbox udkm1Dsim.
In the laboratory course, "High Harmonic Generation," you will learn how to efficiently generate and characterize extreme ultraviolet (XUV) radiation using femtosecond laser pulses. Specifically, you will measure and calibrate the HHG emission spectra and determine the spatial coherence using different double slit samples.
udkm1Dsim - A Python toolbox for simulating 1D ultrafast dynamics in condensed matter,
The udkm1Dsim toolbox is a collection of Python classes and routines for simulating the thermal, structural, and magnetic dynamics of one-dimensional sample structures following ultrafast laser excitation. It further enables the calculation of the corresponding light and X-ray scattering response, providing a unified framework for modeling coupled ultrafast dynamics and their experimental observables. This course provides an introduction to the structure of the toolbox, its workflow, as well as running "real-world" examples, especially for reproducing actual ultrafast magnetism experiments.
