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.

Efficient acceleration and manipulation of high-brightness electron beams using terahertz waves in a compact setup has been recently a hot research topic in acceleration community. Previous works have achieved multi-MV/m acceleration gradient and dozens of keV energy gain while leaving room for further improvements in the high-energy regime. Here, we experimentally demonstrate whole-bunch acceleration and cascaded terahertz-driven acceleration of a relativistic beam with a record energy gain of 204 keV. A terahertz-driven all-optical electron source is now under development, which hold great potential for terahertz-driven ultrafast electron diffraction and related scientific discoveries.
