This five-day set of short courses will be devoted to X-ray Photoelectron Spectroscopy (XPS/ESCA) and the processing of XPS spectra.The first 3 days will be on X-ray Photoelectron Spectroscopy (XPS/ESCA) including Data Processing. It will cover in detail the principles of XPS, instrumentation, imaging, qualitative and quantitative analysis, artifacts in spectra, and depth profiling

Epoxidharzformstoff, Koronaentladungen, Erosion, UV, XPS, ESCA . Kurzfassung: « Corona discharges near the vicinity of the insulating material surface can lead to erosion and limit the life time of the insulators. Epoxy resin insulating material used for high voltage insulators was investigated with a new test setup with the aim to better understand the mechanisms of erosion and to identify. Prevac offers Ambient Pressure XPS (ESCA) system, a new dedicated system developed for ambient pressure 1mbar - 10-10 mbar XPS (ESCA)/UPS experiments with controllable sample temperature ranging from 100K to 850K in analysis chamber.. The Ambient Pressure XPS (ESCA) system comes with full PLC protection and software control including data acquisition and control of all integrated devices.
