SOLEIL recently launched an ambitious project which aims at producing synchrotron radiation pulses of 100 femtoseconds width: the femto-slicing project. The first beamlines concerned will be TEMPO (photo-emission) and CRISTAL (diffraction). CCPM (Marseille), the CRG D2AM beamline at ESRF and the Detectors group at SOLEIL have designed and produced one of the detectors needed for the future experiments carried out on CRISTAL beamline.
