Description
XPD project - photon data base for the European XFEL is a joint effort of DESY and European XFEL*. The project has been launched in 2009, and is in use by users since 2012. The goal of the XPD project is to provide users with full temporal, spatial, and spectral patterns of the radiation fields for different regimes of the European XFEL operation. Tracing of these fields with advanced user simulation tools from the source (undulator) via photon beam line (mirrors, gratings, etc) with subsequent simulation of user experiment (interaction with a sample, simulation of physical processes, simulation of detection process of related debris like photons, electrons, and ions) is of key importance for planning future user experiments. Full 3D maps of the radiation fields are stored in the mass storage service dCache (disc cache system) at DESY. A web application (https://in.xfel.eu/fastxpd) allows to pick up a selected photon pulse data in the HDF5 format for any given XFEL operation mode (electron energy, charge/photon pulse duration, active undulator range etc) suitable for statistical analysis, propagating through the optical system, interaction with the sample, etc.
