Performing polarimetry in the soft X-ray range, from 1 keV to 15 keV, is a topic of high interest in the astrophysical community. However, for instrumental reasons, soft X-ray polarimetry has been performed only once so far by a mission on board the

We report on the x-ray absorption of Warm Dense Matter experiment at the FLASH Free Electron Laser (FEL) facility at DESY. The FEL beam is used to produce Warm Dense Matter with soft x-ray absorption as the probe of electronic structure. A multilayer

International audience; Following the theoretical predictions, the observation of two-photon processes by interaction of vacuum ultraviolet (VUV) radiation with inner-shell levels of atoms requires focused intensities in the 10^13-10^14 W/cm^2 range.

International audience; High harmonic amplification is shown in an optical-field ionized X-ray laser. The 4d–4p X-ray line of Kr^8+ at 32.8 nm, which has a close match to the 25th harmonic of the infrared laser, was amplified up to 200 times. The e

Hard X-ray micro-tomography is a powerful tool to reveal the internal structure of thick objects in a non-destructive manner. For synchrotron applications and practical lab works with students, a 2D detector based on a thin YAG:Ce scintillator optica
