Abstract
We present first results of the high-repetition-rate beamline for time- and angle-resolved photoelectron spectroscopy (Tr-ARPES). The laser parameters are 150-200 µJ energy at 100 kHz, 50-100 fs duration and tuneable wavelength of 1450-1850 nm or 250-3680 nm. The extreme ultraviolet probe parameters are 17-41 eV photon energy, 150 meV spectral, 70 fs temporal, and 35 µm spatial resolution.
