Electron Spectrometers

VG Scienta’s strong tradition in instrument development has its roots in the Nobel Prize winning achievements of prof. K. Siegbahn. The skills and traditions inherited and carried on from the early days of ESCA (Electron Spectroscopy for Chemical Analysis) has been well nurtured and resulted in a variety of new innovative top-performing instruments. The continuous output of state-of-the-art electron analyzers, along with their stable performance and very long life time, is well reflected in the large amount of publications in high ranked scientific journals.

The VG Scienta electron spectrometers are available in different sizes and shapes to satisfy different applications and scientific interests. The hemispherical electron analyzers are the Scienta R4000 with a 200 mm mean radius and the Scienta R3000 with a 135 mm mean radius. These come in a variety of models with a multitude of options regarding everything from angular capabilities and energy ranges to detector type. The ARTOF 10k (Angular Resolved Time Of Flight) spectrometer is principally different from the R4000 and R3000 spectrometers but serve the same purpose as it brings state-of-the-art angle resolved photoelectron spectra to the scientists. More information about the spectrometer types and models is found by navigating in the product list.

One of the most appreciated Scienta instrument undertakings is the development of spectrometers capable of measuring kinetic energy and emission angle simultaneously (Angular Resolved Photoemission Spectroscopy or ARPES, ARXPS, ARUPS). This has for example led to a breakthrough in the studies of superconducting materials. For this achievement VG Scienta’s Dr. Wannberg was awarded the Keithley award for instrument development at the 2008 APS March meeting. The high energy resolution and transmission of the instruments has also allowed insights to be gained in a wide range of materials, including not only solid state samples but also gases and liquids. The recent development of a spectrometer capable of measuring very high kinetic energies has led to an exploration of a new field, HAXPES (Hard X-ray Photoelectron Spectroscopy). At the low kinetic energy end of the scale, a new instrument (the ARTOF 10k) has been launched for Laser-ARPES measurements. VG Scienta has recently also developed a HiPP set-up (High Pressure Photoelectron spectroscopy) for ambient pressure studies.
