In this paper, the authors present the characterization experiments of a 20fs vacuum ultraviolet beam from a high harmonic generation source. The beam hits a silicon sample and passes a triple reflection gold polarizer located inside an ultrahigh vacuum chamber. The polarizer's Malus curve was obtained, the total acquisition time for each point of the curve was 30s. This aims to be the first vacuum ultraviolet time-resolved user station dedicated to ellipsometry. The high harmonic beam is generated by a 12mJ, 1kHz, 20fs, in-house-developed laser and detected by a back-illuminated charge-coupled device.
