  For the latest generation of detectors transmission, persistence and reading of data becomes a bottleneck. Following the traditional pattern acquisition-persistence-analysis leads to a massive delay before information on the data is available. This prevents the efficient use of beamtime for users. Also, sometimes, single nodes cannot keep up in receiving and persisting data. PSI is breaking up with the traditional data acquisition paradigm for its detectors and is focusing on data streaming, to address these issues. Data is immediately streamed out directly after acquisition. The resulting stream is either retrieved by a node next to the storage to persist the data, or split up to enable parallel persistence, as well as online processing and monitoring. The concepts, designs, and software involved in the current implementation for the Pilatus, Eiger , PCO Edge and Gigafrost detectors at SLS, as well as what we are going to use for the Jungfrau detector and the whole beam synchronous data acquisition system at SwissFEL, will be shown. It will be shown how load-balancing, scalability, extensibility and immediate feedback are achieved, while reducing overall software complexity.

  Recently, the installation of the components for the free electron laser SwissFEL has started at the Paul Scherrer Institute (PSI). In March 2016, beginning of the injector commissioning is planned and first lasing is foreseen a year later. New hardware, like VME64x-boards (IFC 1210, an P2020 based intelligent FPGA controller from IOxOS) and -crates (Trenew), timing system (from MRF with advanced features), motion controllers (Power PMAC from Delta Tau, and MDrive from Schneider), among others, as well as modern field buses, pose great challenges to the controls team. The close interaction of machine- and experiment-components require advanced software concepts for data-acquisition, -distribution, and -archiving. An overview of the project will be presented and the different HW and SW solutions based on the experience gained from preliminary implementations at other facilities of PSI will be explained. First results of the HW commissioning at the SwissFEL will be reported.
