CoSMoS: Combined spectroscopy and microscopy on a synchrotron (PES, MBE, STM)

A complex cluster for surface and interface science (Specs, Fig. 3), delocalized actually on the SuperESCA beamline at the Elettra synchrotron radiation facility in Trieste (Combined Spectroscopy and Microscopy on a Synchrotron – CoSMoS), composed by: (i) a chamber for photoelectron spectroscopy (XPS, ESCA, UPS, AES) with angle and spin resolution (ARPES, XPD, ARUPS, SR-UPS); (ii) a molecular beam epitaxy (MBE) chamber with in situ follow-up by low energy electron diffraction (LEED) and reflection high energy electron diffraction (RHEED) and residual gas analysis; (iii) a chamber for scanning tunneling microscopy and spectroscopy (STM/STS); (iv) load-lock and storage of samples in ultrahigh vacuum. This installation have allocated each semester from Elettra 5 days of „in-hous research” beamtime and 6 days of beamtime allocated based on research projects, reserved only from projects from Romania. In addition to synchrotron radiation beamtime, photoelectron spectroscopy using laboratory sources, or other experiments STM/STS, LEED, RHEED, Auger, etc.are possible at any time, provided the personnel is able to travel at Elettra.
