DetailPHOIBOS 150 EP MCD
State of the art hemispherical energy analyzer with MCD-9 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.
