  Coherent radiation is a powerful scheme for storage-ring-based synchrotron radiation sources as its intensity increases with the square of the number of radiating electrons. Formation of bunches or sub-bunches shorter than the radiation wavelength, i.e., microbunching, is necessary for the radiation from different electrons to add in phase and therefore cohere. Recently at the MLS it has been shown that in dedicated isochronous optics an electron beam energy modulation induced by an externally applied 1064-nm-wavelength laser in an undulator leads to the formation of sub-um microbunches one turn later*, providing the basis for the implementation of steady-state microbunching in electron storage rings to generate high-repetition, high-power coherent radiation. Here we report on the recent progress and continuing development of this experiment.

  HZB operates and develops two synchrotron radiation sources at Berlin Adlershof. The larger one, BESSY II with an energy of 1.7 GeV and 240 m circumference is optimized for soft-X rays and in operation since 1999. The smaller one is the MLS (Metrology Light Source), owned by the Physikalische Technische Bundesanstalt (PTB) - Germany’s National Metrology Institute. It is designed to fulfill the special metrology needs of the PTB with an energy of 0.6 GeV and 48 m circumference, covering the spectral range from THz and IR to EUV/VUV. In 2020 a discussion process has been started to define the requirements for successors of BESSY II and MLS and to study the possibilities integrate them into a new photon science facility in Berlin Adlershof. Here, we give a status report and present a first envisaged parameter space to both machines (see also MOPAB262, MOPAB220, MOPAB048, MOPAB242).
