Scienta Omicron's HAXPES Lab brings hard X-ray photoelectron spectroscopy (HAXPES) capability directly to the local laboratory environment. This novel system probes bulk sample properties and accesses deep core level electrons via photoelectron spectroscopy (XPS) without the need for a synchrotron end station. Using world class technology and expert engineering, the HAXPES Lab sets the standard for laboratory based high energy photoeelectron spectroscopy.

Photoelectron spectroscopy is a well-established tool for analyzing a wide range of chemical and material properties. Traditional photoelectron spectroscopy instruments employ low energy X-ray sources limiting the kinetic energy of the photo-emitted electrons. This kinetic energy provides short mean free paths, confining analysis by traditional instruments to the top several nm's of a material's surface. HAXPES, using higher kinetic energies, greatly extends the analysis depth. While HAXPES measurements have been successfully deployed at synchrotrons, obtaining access to the required end stations is a significant challenge. The HAXPES Lab solves this problem and serves as a complete analytical tool bringing cutting edge HAXPES directly to the end user's laboratory.

The HAXPES Lab provides an unprecedented opportunity to study the full range of forefront materials. Novel measurements of bulk electrical and chemical properties are now possible. Advantages of the HAXPES Lab include the ability to easily execute a chemical analysis of real world samples without the need for potentially destructive surface preparation, or to evaluate the properties of buried layers in energy harvesting devices and batteries.
