We report the status of the LWFA driven X-ray sources at ELI beamlines facility. Gammatron beamline, that covers the X-ray energies from 1-100 keV in betatron scheme, and up to a few MeV in Compton scheme will be implemented in the Experimental hall E2. A state-of-the-art Ti:Sa diode-pumped HAPLS laser system (L3 laser) generating laser pulse of less than 30 fs, with energies of up to 30 Joule and with repetition frequency of 1-10 Hz would be used as a driving laser for these X-ray sources. The Betatron source will be broadband while Compton source would be quasi monoenergetic or broadband. These sources are characterized with a low divergence (< 20 mrad), small source size (few μm), short pulse duration (a few fs) and photon flux up to1010 photons per pulse. The Gammatron beamline will open new horizons in ultrafast X-ray science.
Experimental hall E3 (Plasma Physics Platform) houses a separate betatron source with similar properties to the one in E2. It will be an excellent source for probing various types of laser-generated plasmas and warm dense matter or other high-energy density physics phenomena.
Besides the presentation of the two X-ray sources we will also introduce a new optical probing method with increased interferometric sensitivity for characterization of low-density gas jets. This method was employed for characterization of a low-density argon gas jet at various backing pressures and the results were compared to commonly used Mach-Zehnder interferometer setup using a 405 nm laser.
