We present a high harmonic generation source driven by a nonlinearly compressed 50-100 kHz fiber laser enabling record high >1011 photons/s in single harmonics between 55-73 eV. The unique capabilities of the source are underlined by using it for coincidence experiments in gas phase CH3I and measurements of the transversal magneto optical Kerr effect in nickel and iron samples.
