NAP-XPS System Backfilling
The NAP-XPS System Backfilling configuration enables customers to perform state of the art research with the highest possible scientific output. In the backfilling configuration the entire vacuum chamber, accommodating the sample, excitation source, and analyzer, serves as the reaction cell. In this setup the entire chamber is filled with desired gas atmosphere. The advantages of the setup are its flexibility and simplicity. Different excitation or preparation sources can be installed that point towards the sample in measurement position. Furthermore, the electron analyzer and, even more important, the sample manipulator can be mounted in different orientations. In this way, a horizontal orientation of the sample during measurement is maintained, which allows for performing measurements on loose powder samples or even liquids.
The system is highly modular and can be upgraded with different sample preparation facilities as well as additional investigation methods like Infrared-Reflection-Absorption Spectroscopy (IRRAS), NAP-SPM, etc. The NAP-XPS system with backfilling configuration can be built as an end station for synchrotrons, as a laboratory system as well as a hybrid system (for synchrotron and laboratory use).
