µ-spot ARXPS System

µ-spot ARXPS System is designed to perform angular resolved XPS analysis with a combination of a µ-spot  X-ray source, a µ-FOCUS 350 with Rowland circle diameter of 350 mm and an achievable µ-spot size of 50 µm, and a PHOIBOS 150 WAL (Wide Angle Lens) Analyzer. A single aluminum anode is fitted as standard.

It provides the scientist with an optimized solution.  The system allows to start with a basic configuration for µ-spot ARXPS and expand with upgrade options towards improved performance or expansion to more additional methods. This means the system can grow depending of additional requirements and needs.

The possibility of coupling the system to other UHV systems as well as adapting the system for fulfilling customized criteria is also available.

The system basis consists basically in the following items:

• µ-metal analysis chamber
• PHOIBOS 150 WAL Analyzer (wide angle lens analyzer) with 2D detector
• Manipulator with until 5 axis movement option and heating and cooling option
• Ultra small spot X-ray source (µ-FOCUS 350)
• Water Cooling System for Source and pumping system
• Load lock chamber for sample introduction with sample storage and sample heating options
• Extension possibility for possible preparation or reaction chamber
• Pumping system
• Bake-out System
• Electronic
• SPECS software for data acquisition, data analysis, remote control and automation possibility

Additional and optional items
