Data acquisition automation
- automation of angle-resolved experiment- spectra acquisition- sample rotation control
- data processing and visualization- fast processing and fitting of thousands spectra- visualizations specific for each method and mode
KolXPD & X-ray photoelectron diffractiontree view of multiple
experiments
spectra for each angle step(multiple regions in one step)
polar or azimuthal scans of XPD pattern
2D view of XPD pattern(Cartesian or polar)Angle resolved spectra can be fitted
- all angular points are automatically fitted- any parameter of the fit or an expression of them
can be drawn in scan chart or 2D-pattern view

KolXPD: Other capabilities• measurements of methods using variable photon energy
(NEXAFS, resonant photoemission, etc.)at MSB beamline (synchrotron Elettra in Trieste, ITA)
• fast processing and visualization of standard photoemission data (XPS, UPS and SRPES methods)
• import of result of XPD-pattern simulations (software EDAC*)• simple quantitative analysis• import and export of many file-formats
