PHOTON SCIENCE

• The Petra III experiments are controlled by Tango, the hardware access and transport layer, and Sardana for the user interfaces including CLI, scripting and GUIs. A document describing the DESY-specific Sardana implementation can be found here.
• Tango servers are written for all devices employed by Petra III experiments.
• FS-EC is the mediator between FS and DESY-IT in the data management area. The main parts are data transfer, data storage, data archive, data export and data processing.
• ICS is a Web interfaces to operate the personal safety interlock system at the beamlines.
• DOOR, the DESY Online Office for Research with Photons supports all steps necessary to submit proposals and to apply for beamtimes. This service is a collaboration with DESY-IT.
• The electronics subgroup provides various services for the DESY-FS, including new developments.
• Support for PC hardware and selected VME modules and other devices.
• LaVue is the standard 2D visualization tool for the Petra III experiments. It includes many useful features.
• A c++ NeXus library including Python bindings and related tools has been created and is further being developed.
• NeXus/HDF5 is currently being integrated into the experimental procedures, including the adaptation of modern high-speed detectors. Details can be found in the Sardana NeXus Recorder  chapter of this manual.
• Various analysis tools are available for Photon Science users.
• OS support: FS-EC uses DESY-IT services to prepare ready-to-use Windows and Linux PCs. Specific applications are installed on request. Experiment PCs require a management of the control software.
• Various members of FS-EC function as DESY group administrators.
• A weekly meeting facilitates the communication between BL staff and FS-EC.
• Various IT and Experiment Control related topics are covered in DESY Confluence.
• Users may report issues to a request tracker.
