A new Data Acquisition system is being developed and commissioned for the upcoming FEL at PSI. This system is based on several novel concepts and technologies, and it targets at immediate data availability and online processing. The system is capable of assembling an overall data view of the whole machine thanks to the distributed and scalable buffering back-end. Load on data sources is reduced by immediately streaming data as soon as it becomes available. The streaming technology used provides load balancing and fail-over by design. Data channels from various sources can be efficiently aggregated and combined into new data streams for immediate online monitoring, data analysis and processing. The system is dynamically configurable, various acquisition frequencies can be enabled and data can be kept for a defined time window. All data will be available and accessible enabling advanced pattern detection and correlation during acquisition time. Accessing the data in a code-agnostic way will also be possible through the same REST API that is used by the web-frontend. Furthermore, data can be automatically reduced, compressed and extracted for later studies and documentation.
