Implementation and characterization of a new two-dimensional position sensitive electron detector for the ARPES-TPES end station

This technical report contains a detailed description of the implementation and commissioning of a bidimensional electron detector in the ARPES-TPES end station, an experimental apparatus for gas phase photoemission experiments located at the Elettra Synchrotron in Trieste. The collaboration between the CNR - IOM of Trieste institute, the Sapienza University of Rome, and the Elettra Instrumentation and Detector Laboratory, has resulted in the development of a position sensitive cross delay line electron detector and a new type electrode for correcting fringing field effects. These two systems were integrated in the experimental apparatus to perform synchrotron radiation photoemission experiments on gas phase molecular systems. The improvement of the apparatus detection system has stimulated the collaboration with the Theoretical Chemistry group of the University of Trieste, in a joint experimental and theoretical long-term research activity.
