New sample holder for XPEEM with an optical focusing lens — •Lukas Gierster^1,2, Leo Pape³, Akin Ünal², Sergio Valencia², and Florian Kronast² — ¹Technische Universität Berlin — ²Helmholtz-Zentrum-Berlin (BESSY) — ³Ernst-Moritz-Arndt-Universität Greifswald

We describe a new sample holder for the X-Ray Photoemission Electron Microscope (XPEEM) which enables focusing femtosecond Laser pulses to their diffraction limited spot sizes (i. e. 1-2 µm). With this sample holder we can create local and ultrashort excitations in magnetic systems. The spread of excitations in lateral as well as temporal dimensions can be investigated using the XPEEM magnetic imaging technique at Bessy II synchrotron.
