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.
This product is discontinued
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.
