Multichamber ARPES UHV system [project 072]



The system is designed for ARPES research. It consists of a moveable frame and four chambers. The frame allows precise positioning of the system in all three axes. Each chamber has its own dedicated pumping system with the exception of the Preparation chamber, which is connected to, and pumped via, the distribution chamber). The system can be easily extend in the future to add e.g. an MBE chamber.


The system is equipped with a high-resolution photoelectron spectrometer with exceptional parallel detection, enabling an energy resolution of 1.4 meV and an angular resolution of 0.2°.

The high precision 5-axis motorised sample manipulator in the analysis chamber is equipped with a He cryostat and a high precision sample distribution stage. A load lock and sample preparation chamber complete the system to form a rugged experimental station.

The manipulator allows angle-resolved measurements over 2 p steradian below 10K. The system is engineered to be controlled completely by a touch-screen menu. Sample manipulation inside the system is facilitated by a specially designed high precision transfer mechanism.
