Old text: The HIPPIE end station is designed for Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS) offering the possibility of recording photoemission spectra at pressures up to 30 mbar (currently 10 mbar). The endstation consists of an analysis chamber equipped with a hemispherical Scienta-Omicron HiPP-3 electron energy analyser. An ambient pressure experimental cell (AP Cell) can be docked to the analyser for ambient pressure experiments. When the AP cell is retracted UHV experiments can be performed. The analysis chamber is also equipped with a  Bruker PM-IRAS instrument for simultaneous recording of APXPS and PM-IRAS at 1 mbar; likewise, the composition of gas/vapour introduced in the AP cell and pumped out from it can be monitored by mass spectroscopy. Further the end station contain a preparation chamber, load lock, and UFO distribution chamber.

The Catalysis Cell allows samples to be introduced via UHV following treatment of the surface in the dedicated preparation chamber. The cell can also be retracted allowing UHV measurements in the analysis chamber. This system can incorporate a PM-IRRAS setup for simultaneous recording of APXPS and PM-IRAS at up to 1 mbar. Likewise, the composition of gas/vapour introduced in the AP cell and pumped out from it can be monitored by mass spectroscopy. Technical information detailing the capabilities of the preparation, analysis, load-lock and storage chambers are detailed below. Samples, mounted on flag sample holders with a thermocouple connection, are transfered throughout the system using a UFO distribution chamber.

The Electrochemical / Liquid Cell provides a flexible environment for in-operando electrochemical measurements of solid-liquid interfaces, using a “dip and pull” setup, as well as measurements of liquid-gas interfaces through a liquid jet system. The flexible nature of this chamber, which is separate from the rest of the UHV system at HIPPIE, makes it well suited for measurements requiring fully customised sample environments.
