PHOIBOS 150 EP 1D-DLD

State of the art hemispherical energy analyzer with 1D-DLD detector for photoelectron spectroscopy measurements (XPS and UPS) in the pressure regime from UHV to elevated pressure regime (EP) up to 1 mbar.

The PHOIBOS 150 EP analyzer is an integral part of all PHOIBOS 150 NAP analysers, but in contrast to the NAP version is operating without the wide acceptance angle pre-lens. Therefore, it has 3 diferential pumping stages and can operate at pressures up to 1 mbar. The first differential pumping stage is separated from the analysis chamber by a nozzle with a customizable opening at the tip with diameters between 0.3 mm and 5 mm.

Depending on its configuration the PHOIBOS 150 EP can perform XPS und UPS measurements at pressures of up to 1 mbar. It offers full flexibility to be equipped with all available 1D and 2D detectors. The modular building concept enables the user to upgrade a PHOIBOS 150 EP to a full PHOIBOS 150 NAP analyzer by simply adding the pre-lens together with the corresponding electronics and additional differential pumping.

KEY FEATURES

  • Elevated working pressures up to 1 mbar depending on configuration
  • Upgradeable to complete PHOIBOS 150 NAP analyser including wide acceptance angle pre-lens
  • Up to 30° acceptance angle in angle in resolved and transmission mode
  • High energy and angular resolution
  • Working range up to 3.5 keV
  • Large pass energy range
  • 3 differential pumping stages
  • Fast detectors with high dynamic range for fast real time data acquisition in snapshot mode
  • Full detector flexibility (MCD, 1D-DLD, 2D-DLD, 2D-CCD/-CMOS)
