SuperESCA beamline description

The experimental apparatus is controlled via a LabVIEW^TM based software, developed by the beamline staff. The program fully controls the instrumentation in the experimental chamber: besides  photoemission spectra acquired by the electron energy analyzer, for each data set the software registers also the sample temperature, the pressure in the chamber and a reference current for flux calibration. In case of photoelectron diffraction measurements, the program guarantees

the synchronization between sample rotations and spectra acquisitions.
Moreover the program  interacts also with the Elettra Beamline Control System (BCS) for setting undulator gap and changing the photon energy, allowing in this way the maximum flexibility for different kinds of experiments.
