Photon Science 2019

During the last few years the developments in our field have gained additional momentum. Not only do new ideas emerge to further improve synchrotron and free-electron laser (FEL) radiation sources but this also holds for the experimental techniques including new types of highly performing detec-tors. The entire field is extremely competitive and it requires considerable effort to stay at the forefront. DESY is intending to meet this challenge with a very ambitious plan for the upgrade of its photon science facilities as well as the associated infrastructure.
