CompactLight (XLS) is an International Collaboration of 24 partners and 5 third parties, funded by the European Union through the Horizon 2020 Research and Innovation Programme. The main goal of the project, which started in January 2018 with a duration of 36 months, is the design of an hard X-ray FEL facility beyond today’s state of the art, using the latest concepts for bright electron photo-injectors, high-gradient accelerating structures, and innovative short-period undulators. The specifications of the facility and the parameters of the future FEL are driven by the demands of potential users and the associated science cases. In this paper we will give an overview on the ongoing activities and the major results achieved until now.

A Soft X-ray Laser project (the SXL) aiming to produce FEL radiation in the range of 1 to 5 nm is currently in a conceptual design phase and a report on the design is expected to be delivered by March 2021. The FEL will be driven by the existing 3 GeV linac at MAX IV laboratory, which also serves as injector for the two storage rings. The science case has been pushed by a large group of mainly Swedish users and consists of experiments ranging from AMO physics to condensed matter, chemistry and imaging in life science. In this contribution, we will present the current conceptual design of the accelerator and the FEL operation modes together with a general overview of the beamline and experimental station. In particular design options for the FEL will be discussed in conjunction with the features of the electron beam from the MAX IV linac and the connection with the proposed experiments.

From Femtosecond to Attosecond Coherent Undulator Pulses

In Bohr’s model of the hydrogen atom, the ground-state electron completes one cycle of revolution in 150 attoseconds. Some other processes in atoms and molecules can be even faster. Femtosecond and attosecond pulses of light can provide the resolution needed for studying and ultimately controlling the dynamics of electrons in solids, molecules and atoms. Therefore, there is a strong scientific demand for the development of sources of high-energy, ultrashort, coherent, X-ray pulses. In this talk, we (i) review the characteristic time and length scales in atoms, molecules and nanostructures, (ii) outline the progress on short-pulse generation over time and the state-of-the-art of production of high-energy, ultrashort pulses; (iii) examine the demonstrated and proposed schemes of the generation of femtosecond and sub-femtosecond pulses with FELs, (iv) discuss recent concepts [1] for the production of 100-attosecond pulses.
