Introduction to X-Ray Sources X-ray Photoelectron Spectroscopy (XPS) is a routine surface analysis technique used to quantitatively analyse the chemical composition of the surface of a sample. For such studies two types of X-ray source exist the 'twin anode1 X-ray source for high speed, large area XPS and the 'monochromated' X-ray source for ultimate energy resolution. Other XPS techniques in which Omicron X-ray sources may be used include Angle Resolved XPS (AR-XPS), Depth Profiling, Multi-sample and large sample analysis and Small Area defined XPS (SAXPS). Omicron offers two dedicated...

XPS is one of the few techniques able to offer the researcher both elemental and chemical state information in a quantifiable form. Both twin anode and monochromated sources are able to provide standard XPS information but the use of monochromated X-rays may provide a number of research advantages for some operators. • Improved energy resolution; allowing the researcher to define the chemical peaks more precisely due to the narrower energy spread of the X-ray beam. A typical high per- formance monochromated X-ray source will have a photon line width of below 300meV, compared to ~850meV for...

DAR 400 Al window The DAR 400 is a twin anode X-ray source designed for high stability XPS performance with both Al K and Mg K radiation. The latest design philosophy offers the user: Anode fence Anode 1&2 • High power (up to 400 W) • Continuously adjustable anode voltage (up to 15 keV for sensitive damaged materials) • Minimal radiation cross talk (<0.35%) • Optional linear drive and port aligner for minimum working distance and multitechnique integration • Thoria-coated Tungsten cathodes, providing increased lifetime, stability and emission The DAR 400 is operated via the advanced digital...

XM 1000 The XM 1000 monochromated X-ray source is based on a compact 500mm diameter Rowland circle design, allowing it to be fully integrated into any ESCA solution with no compromises in performance or geometry. Quartz crystal x-ray mirror The XM 1000 offers leading performance with high photon brightness and a line width of below 0.25 eV. The Thoria coated Tungsten cathodes allow operation in high power line mode (600 W) and spot mode (300 W) delivering both high count rate and experimental exibility. Omicron’s 'All UHV' design philosophy means that the XM 1000 is thermally compensated to...

gjj Omicron X-ray 554 Control Windows™ 'drag-and- drop' technology allows control of their ESCA Optional Source Automation within CASCADE power supplies provide the user full software control over both X-ray sources, either individually ration of both sources using the 554-D digital supply provides the operator a space and cost saving, single digital interface and ensures accurate control of the anode cooling via a single recirculating water chiller. The new control software allows the user to operate either of the 554 series electronics remo- tely via PC interface including advanced...
