Time-resolved X-ray microscopy is a powerful imaging technique that has been extensively employed for the study of dynamical processes in condensed matter systems. In particular, time-resolved scanning transmission X-ray microscopy (TR-STXM) has been the workhorse in the experimental study of magneto-dynamical processes such as magnonics, switching, domain wall motion, and the dynamics of topological magnetic objects.
In this contribution, we will present the current status and outlooks of TR-STXM imaging at soft X-ray energies. The TR-STXM setup of the Swiss Light Source (SLS) will be presented, together with examples of 3D TR-STXM imaging, of periodogram-based imaging, and of how to overcome the limitations given by the X-ray pulse width.
In addition, we will present the planned future developments of the technique in view of the significant increase of coherent photon flux that will be offered by the upgrade of the SLS to a diffraction limited storage ring.
