Custom-designed UHV system that consists of two independent UHV chambers: a preparation/analysis chamber and an electrochemical (EC) chamber. Both chambers are connected through an UHV-EC transfer system. This XPS-EC system allows to combine in situ XPS and electrochemical measurements in order to determine the chemical changes induced in the materials due to the electrochemical work.
Custom-made XPS-UHV system equipped with a high precision VT manipulator (RT – 1000 K) capable of x,y,z translations, polar rotation and azimuthal rotation with an angle resolution better than 0.5°. This system is able to do the mapping of the intensity of a selected photoemission line over the entire 2pi hemisphere above the sample (XPD capability). The analyzer can operate both in constant analyzer energy mode (XPS experiments) and constant retard ratio mode (AES measurements). In addition, it is coupled with an scanning tunelling microscope (STM) for morphological characterization at atomic level.
Custom-made XPS system designed for catalysis studies from 110 to 1000 K thanks to the Hidden Quadrupole Mass Spectrometer for Temperature Programmed Desorption (TPD) measurements.
