Design of tabletop high harmonic beamlines for dynamic magnetic spectro-microscopies

High harmonic sources in the extreme ultraviolet (EUV) region of the spectrum are being adopted for applications in magnetic spectro-microscopies, since they enable element-specific probes of the fastest spin dynamics in alloys, multilayers and topologically protected materials. Simultaneously achieving high EUV flux, stability and polarization and phase structure requires careful design. We will review two beam line designs that are optimized for resonant magnetic scattering and EUV magneto-optical spectroscopies, as well as their applications in probing multilayer, alloys, metalattice and skyrmion samples. We will also review capabilities of high harmonic generation to produce structured EUV beams.
