Journal Article
The Aragats data acquisition system for highly distributed particle detecting networks
2008
Overview
For a reliable and timely forecast of Space Weather world-wide networks of particle detectors are located at different latitudes, longitudes and altitudes. To provide better integration of these networks the data acquisition system is facing a challenge to establish reliable data exchange between multiple network nodes which are often located in hardly accessible locations and operated by small research groups. In this article we want to present a data acquisition system for new establishing SEVAN (Space Environmental Viewing and Analysis Network) elaborated on top of free open-source technologies. Our solution is organized as a distributed network of uniform components connected by standard interfaces. The main component is URCS (Unified Readout and Control Server) which controls frontend electronics, collects data and makes preliminary analysis. The URCS operates fully autonomous. Essential characteristics of software components and electronics are remotely controllable via a dynamic web interface, the data is stored locally for certain amount of time and distributed on request to other nodes over web services. To simplify data exchange with collaborating groups we are using an extensible XML based format for data dissemination. The data acquisition system at Aragats Space Environmental Center in Armenia was started November, 2006. Seven particle monitors are located at 2000 and 3200 meters above sea level at a distance of 40 and 60 km from data analysis servers in Yerevan, Armenia. The reliability of the service was proofed by continuous monitoring of incident cosmic ray flux.
