HIGH PERFORMANCE WEB APPLICATIONS FOR PARTICLE ACCELERATOR CONTROL SYSTEMS

The integration of web technologies and applications has been one of the major trends for the development of new services for Control Systems (CS) of particle accelerators and large experimental apparatuses. Nowadays, high performance web technologies exhibit some features that would allow their deeper integration in a CS and their employment in developing CS’ core components. In this paper we discuss the results of preliminary investigations of a new paradigm for a particle accelerators CS and the associated machine data acquisition system based on a synergic combination of network distributed cache memory and a non-relational key/value database. Storage speed, network memory data retrieve throughput and database queries execution, as well as scalability and redundancy of the systems, are presented and critically reviewed.
