Recent experiments have shown that the high-temperature incommensurate (I) charge density wave (CDW) phase of 1T-TaS$_2$ can be photoinduced from the lower-temperature, nearly commensurate CDW state. In a first step, several independent regions exhib

International audience; In the context of lightning strike impacting aeronautical fasteners, we investigate the in situ behaviour of fasteners subject to a current level of a few kA by using high-speed Xray phase-contrast imaging in a synchrotron fac

International audience; Time-resolved pump-probe experiments at SOLEIL Synchrotron (France) have motivated the development of a new and fast photon counting camera prototype. The core of the camera is a hybrid pixel detector, based on the UFXC32k rea
