The Tunnel : combining vacuum surface science techniques

ISMO’s ultra-high vacuum tunnel (10-10 mbar), installed in 2019, brings together a wide range of complementary techniques for vacuum surface analysis such as optical (SFG, FTIR) and electronic spectroscopy (HREELS, XPS, UPS), local probe microscopy (STM, AFM) and atom (GIFAD) and electron diffraction (LEED). The tunnel allows the preparation (cleaning by bombardment, deposition of metals, semiconductors or organic molecules) and the transfer of samples between the different experimental setups.

The interconnection of the new fs laser chain installed at ISMO in 2019 with the ultra-high vacuum tunnel allows the realization of vacuum SFG experiments and the possibility of combining fs laser and local probe microscopy (STM, AFM).

Interconnection between the tunnel and the fs laser : Ti:Sa fs laser (Coherent, Legend Elite) 35 fs, 4 mJ, 3 kHz pumping 3 TOPAS to provide pulses from UV (240 nm) to mid-IR (16 µm) connected to the ISMO vacuum tunnel via the experimental setup of the group Femtophysics at interfaces.
