R3000

A Compact and Powerful XPS/UPS/ARPES Tool with Optimised Transmission

PESARPES

  • Optimised transmission for high intensity
  • High dynamic range
  • Fast and easy experiment optimisation
  • Reliable and reproducible

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 Omicron R3000 is optimised for quick PES measurements and band mapping. The high voltage electronics is designed for ultrahigh stability to enable reliable and accurate measurements. The Scienta Omicron R3000 can be operated in fixed mode, where a spectrum can be recorded within seconds by taking a snap shot of the detector image, covering 12 % of the pass energy. The high count rate of the Scienta Omicron R3000 is accomplished by combining a large acceptance angle, an analyser radius of 135 mm and a MCP detector as large as the one featured in the DA30-L analyser. At the same time the outer dimensions of the spectrometer are small, for easy fit to an existing vacuum system. This is accomplished by using a mu-metal vacuum vessel. The detector has a high dynamic range which, together with powerful noise reduction, enables great experimental results.

The Scienta Omicron spectrometers have always pushed the boundaries of what is possible within electron spectroscopy. These state-of-the-art instruments have for example revolutionised the angular resolved photoemission experiments (ARPES) used to investigate superconductivity. This was achieved by inventing a spectrometer capable of measuring kinetic energy and momentum of photoelectrons simultaneously. The high quality and reliability of the Scienta Omicron spectrometers are most clearly seen by the impressive number of publications in high ranked scientific journals.
