ProvenX-MM

Proven Analysis System for State-of-the-Art Momentum Microscopy

The ProvenX system series represents the quintessence of our extensive knowledge in developing and manufacturing complete surface analysis systems that fulfill the most demanding scientific requirements. This system concept combines the most required analysis techniques with the latest and proven technology for ultimate performance.

The ProvenX-MM system is a specialized systembase for momentum microscopy solutions, supporting the KREIOS 150 Series, parallel single event detectors and optional spin detection, as well as the UVS µFOCAL small spot UV source with optional monochromator. The sample handling is done by the SPECS HESTIA low temperature microscopy stage. The system comes with a dedicated preparation chamber, a clean UHV sample storage facility and a multi sample fast entry loadlock.

System control is done by the SpecsLab Prodigy software suite with integrated remote control packages, automated sample handling and a computer based vacuum control system.

The system can be equipped with an optiopnal small spot x-ray source for material characterization. Additional software and preparation tools are available.
