X-ray Photoelectron Spectroscopy
The AXIS Ultra DLD integrates the Kratos patented magnetic immersion lens and charge neutralisation system with the spherical mirror and concentric hemispherical analysers. Combined with the newly developed delay-line detector (DLD) for both imaging and spectroscopy the AXIS Ultra DLD is the very best spectrometer for analysts requiring unsurpassed performance.
The hemispherical analyser provides both high energy resolution and high sensitivity spectroscopic performance. Exceptional small spot capabilities (<15µm) ar achieved via a series af selected area apertures used in combination with the magnetic and electrostatic lenses. In parallel imaging mode photoelectrons are transferred to the patented spherical mirror analyser which produces real time chemical state images with better than 3µm spatial resolution.
The delay-line detector, comprising a multi-channel plate stack above a delay-line anode, is used for photoelectron detection in both spectroscopy and imaging mode With over 100 detector channels the DLD can also be use to acquire unscanned or 'snapshot' small spot spectra in a matter of seconds. Genuine pulse counting in 2D imaging mode means that quantitative parallel images can now be generated allowing greater insight into the lateral distribution of chemical species at the surface.
