Description
DiProI (Difraction and Projection Imaging) project was born in partnership with scientists and engineers from ELETTRA, LLNL, DESY-CFEL, University of Uppsala, KTH-Stockholm and SLAC, and is based on the transferred know-how accumulated in fixed target, time-delay holography and particle injection imaging at FLASH and now at LCLS. The objectives are exploring material structure, properties and temporal phenomena at nanoscales by simultaneous detection of the scattered diffraction pattern and emitted charged particles from a target with spatial and temporal resolution limited by the FERMI wavelengths and pulse durations. The main characteristics of the experimental station are modularity and high flexibility of the construction, allowing easy replacement of components in order to meet the requirements of the experiments. The planned implementation of point projection imaging is a great challenge but if successful it should facile the iterative inversion of the speckle pattern. Using the tunability and multiple polarization of FERMI, combined with pulse split and delay schemes or external laser, will allow access to the structure of non-periodic targets and stroboscopic imaging exploring dynamic phenomena, such as structural deformation, magnetic domain dynamics, phase separation and nucleation, complex rearrangements of constituents in cells etc. The first commissioning tests of the station using synchrotron light and possible research topics, inspired from the results obtained using synchrotron-based microscopy and imaging techniques, will be briefly discussed.
