ANCHOR-SUNDYN: A novel endstation for time resolved spectroscopy at the ALOISA beamline

In this report we illustrate the instrumental developments involving the branchline of the ALOISA beamline at the Elettra synchrotron, with the setup of the ANCHOR-SUNDYN endstation. The ANCHOR experimental chamber is designed for the study of in-situ prepared organo-metallic hybrid interfaces, by means of synchrotron based soft x-ray spectroscopic techniques. SUNDYN is a femtosecond pulse width laser setup, optimized for the optical pump of organic systems. It has been integrated in the ANCHOR endstation in order to perform time resolved spectroscopies at MegaHertz repetition rate. By combining resonant photoemission spectroscopy and pump-probe X-ray spectroscopies in the same chamber, we can study the dynamics of the electronic structure of organo-metallic interfaces from the femtosecond to the nanosecond timescales. We provide here a detailed description of this setup and discuss some case study measurements obtained during the commissioning of the apparatus.
