Background: High harmonics are ideal as the illumination source for time- and angle-resolved photoemission spectroscopy (trARPES), which can measure the full electronic band structure of a material. Moreover, a new generation of ultrafast (~50-100fs), MHz rep rate, VUV (1-20eV) highly-cascaded high harmonics driven by compact fiber lasers have 10-100meV energy resolution, and are ideal for spin-resolved ARPES (Optica 7, 832 (2020)). Recommended Sources: Hyperion VUV and Pantheon. Specifications: multi-kHz to MHz rep rate; 6 to 80 eV; 10 - 300 fs; 10 10 - 10 14 ph/s flux.
