Accelerator-analytical UHV system [project 412]
An analytical UHV system dedicated for investigation of the chemical and physical properties of solid state surfaces in wide temperatures and UHV conditions.
Analytical system with linear sample transport between chambers (analysis and load lock) under true UHV conditions. The base pressure in the analytical chamber is in range 10-11 mbar. System is prepared to future extensions about radial distribution chamber with possibilities add another process chambers like: preparation, reactor or deposition chamber.
- Spherical multi-technique analytical chamber integrating different surface analysis methods. Sample positioning is via a very stable, high precision, 5-axis manipulator with two rotational axes motorised for automatic angular mapping. The sample receiving station is equipped with a LN2 cryostat that allows temperature variation over the range -180°C to 1000°C (dependent on sample holder model). The chamber is fabricated from mu-metal and equipped with a hemi-spherical analyzer with 2D detector and an accelerator system for light ions with the ion source based on electron cyclotron resonance (ECR ion source).
- UHV vacuum system with combination of turbo molecular pumps, ion pump and titanium sublimation pumps. The hemispherical analyzer is mounted in azimuthal position.
- Load lock chamber.
