High Pressure Photoemission Spectroscopy UHV System [project 487]
![High Pressure Photoemission Spectroscopy UHV System [project 487]](/Media/catalog/product/335/big_487-hp-pes-uhv-system.jpg)
It is quipped with a HP analyser but the focus is on a highly flexible sample environment, partly in form of a newly developed, highly versatile, gas cell, partly in form of the possibility of replacing the analysis chamber with a completely different chamber setup. The station will thus allow for frontier research on gas-solid and gas-liquid interactions. The system is equipped with automated control features to allow for safe and efficient operation of many different types of samples by many different operators.
The heart of the system is the analysis module that is based on the high pressure analyser and a gas cell concept designed by PREVAC.
HP cell 3-axes manipulator design allows for sample heating by IR laser illumination (the sample temperature over 800 °C is reachable within the cell), resistive heating (up to 700 °C) and LN2 cooling (with double Z axes: one for gas cell proper placement and second for high precise sample positioning). For easy disconnection from the gas cell chamber, the manipulator is mounted on the rails.
