With these analysers, spatially resolved chemical state mapping with XPS is possible even at ambient pressures (APPES) and up to atmospheric pressure. Along with analysers specially developed for hard X-rays (HAXPES), these analysers enable XPS research in the fields of catalysis, liquids, and layered materials such as batteries, solar cells, and semiconductor devices.
Analysers for angular resolved (ARPES) applications enable spin resolved electronic band structure mapping across the surface Brillouin zone. These analysers extend the measurement capabilities for phaenomena such as superconductivity, topological insulators, and other interesting quantum materials for spintronic devices.
Besides XPS and UPS, the DA30-L is especially developed for high quality ARPES measurements. Scienta Omicron´s deflector concept enables full cone angular scans in reciprocal space without sample movement. This allows electronic band structure mapping, even spin resolved, of the full surface Brillouin zone without changing measurement geometry, eliminating matrix element effects, and simplifying the interpretation of results dramatically.
The DA30-L-8000 analyser is a progression of the DA30-L analyser optimised for ultra-high resolution at low kinetic energies. Combined with Scienta Omicron´s deflector concept electronic band structure mapping of the full surface Brillouin zone without changing measurement geometry is possible. These are the models of choice for ARPES measurements below 3 eV kinetic energy with high demands for energy resolution.
The DA20 provides ARPES as well as XPS and UPS while maintaining a compact footprint. The DA20 includes the ground-breaking deflection technology that was previously only available in the larger DA30-L analyser models, enabling full cone ARPES measurements without sample rotation. This allows electronic band structure mapping of the surface Brillouin zone without changing measurement geometry, eliminating matrix element effects, and simplifying the interpretation of results dramatically.
The Scienta Omicron HiPP-2 analyser is developed for high pressure photoelectron spectroscopy (APPES) as well as hard x-ray photoelectron spectroscopy (HAXPES). This state-of–the-art analysis tool enables angle-resolved photoemission at ambient pressures up to 50 mbar and kinetic energies up to 10 keV, as well as the combination of the two.
The HiPP-3 analyser features state-of-the-art technology for outstanding imaging XPS at ambient pressures (APPES), with a spatial resolution better than 10 μm. In addition, the unique Swift Acceleration Mode enables unparalleled transmission, with count rates improved by up to a factor of 10.
The EW4000 electron analyser is a state-of-the-art and widely used electron analyser for HAXPES. It is also one of the key parts is Scienta Omicron’s HAXPES Lab. Expanding the parallel angular detection range to 60° in the full range from UPS via XPS to HAXPES gives great possibilities for high transmission measurements as well as novel Standing Wave and XPD experiments.
The Scienta Omicron R3000 is designed to combine minimum size with maximum performance. The R3000 is a high throughput, flexible analyser with high transmission for UPS and XPS applications. The additional angular mode enables mapping of the electronic band structure in ARPES experiments. The R3000 can also be operated in “Fix Mode”, where a spectrum can be recorded within seconds by taking a snap shot of the detector image, covering 12 % of the pass energy. Powerful noise reduction and high dynamic range ensures high quality results.
The Scienta ARTOF 10k analyser marked a revolution in the field of angle-resolved photoelectron spectroscopy (ARPES) for pulsed photon sources with its parallel full cone detection and unchallenged transmission. The Scienta ARTOF-2 is a further development of the concept especially for sources generating harmonics and kinetic energies above 10 eV.
The Argus CU analyser offers outstanding sensitivity, simple handling and maximum convenience during your XPS measurements. In addition, the Argus CU is accurately characterised for quantification and allows spectroscopy with excellent snapshot performance also when operated with large apertures.
The ASPECT Dynamics analyser is a high-end multipurpose photoelectron spectrometer combining unsurpassed count rate performance and new controller technology to allow for advanced XPS studies such as new types of operando experiments and in-situ observations of surface reactions with chemical resolution.
3D Spin VLEED
The 3D Spin VLEED utilises the exchange scattering mechanisms to be 50x more efficient than Mott schemes. It is equipped with Ferrum VLEED detectors which mount on a proprietary transfer lens with high speed switching between channels. The DA30-L's unique deflection mode directs any part the full acceptance cone to the spin detectors without sample rotation for detection of in-plane and out-of-plane spin vectors.
