Secondary sources in E1

High harmonic generation (HHG): This beam line will deliver a coherent collimated beam of photons with energies in the range 10 eV–120 eV.

Plasma X-ray source (PXS): This will be an incoherent source of hard X-ray radiation.

End-stations in E1

MAC: a Multi-purpose chamber for AMO (Atomic, molecular, and optical) sciences and CDI (Coherent Diffractive Imaging).

ELIps: ELI Beamlines VUV ellipsometer for sub-ps experiments; an end-station for VUV and soft X-ray materials science.

Hard X-ray end-station: TREX; a modular station for Time Resolved Experiemnts (scattering, diffraction, spectroscopy and imaging) with X-rays.

Optical probes and pump beams: An advanced station for optical spectroscopy, including stimulated Raman scattering. Also the source for a wide array of synchronized pump beams in the range from UV to IR and THz.

Plasma X-Ray Source (PXS)

The PXS source is based on the interaction of focused ultrashort laser pulses and liquid metal targets. The resulting plasma emits ultrashort, high brightness X-ray pulses with durations of a few hundreds of femtoseconds.

HHG Beam Line

A kHz source of ultra-short EUV pulses emitted in a coherent beam with low-divergence.


MAC is a Multi-purpose chamber that will be used for atomic, molecular and optical (AMO) physics and Coherent Diffractive Imaging (CDI). It can house different types of targets and can be equipped with a range of diagnostic tools.


ELIps is an instrument for femtosecond magneto-optical ellipsometry. It will work in the VUV photon range and employ a fast-switching magnetic field.

X-ray end-stations

The combination of X-ray pulses with sub-picosecond duration and perfectly synchronized and tunable UV-VIS-IR "pump" pulses is the foundation for the development of the end station for X-ray scattering and diffraction (XRD), X-ray absorption spectroscopy (XAS) and phase contrast imaging. Due to the modular design of this TREX area we will be able to switch rapidly between the main experimental modes and even to move parts of the experimental set up to other locations, e.g the Betatron beamline in E2.

Optical probes

Optical probe facility should provide users with the option to pump and probe any process with femtosecond time resolution in any spectral region from 200 nm (near ultra violet) to 10 µm (mid infrared) and also by programmable terahertz waveforms. Pulses can then be spectrally analyzed for transient effects on a shot-to-shot basis with 16-bit dynamic resolution.

Pump beams

Pump beams synchronized with main photon beams will serve for pump-probe experiments to investigate dynamical processes in matter. They will allow flexible configuration at different locations in the E1 hall, covering wavelengths from UV and visible to IR, and THz.
