We introduce a high-harmonic generation (HHG) -based XUV source that offers a broad photon flux range from 40 eV to 150 eV. This source utilizes an industrial-grade TruMicro 2030 laser system with 20-W average power, delivering up to 100 µJ with pulse durations under 400 fs. A post-compression unit is incorporated to reduce the pulses to approximately 40 fs with just a 10% average power loss. The turnkey source achieves a photon flux exceeding 10¹0 photons/s around 70 eV.
