Abstract:

Based on the measurement and control requirements analysis for neutron diagnostics, the design model of Neutron Flux Monitoring was established on Enterprise Architect platform. According to the ITER Instruments and Control framework, the detailed functional analyses of signal conditioning, operational control, measurement and processing were conducted based on use cases and extended user and system requirements. The automatic operation processes of plasma discharge, equipment maintenance and system acceptance test were adopted by function mapping. The preliminary design of Neutron Flux Monitoring system was finished, whose hardware and software architectures conform to the ITER control, data acquisition and communication specification, and meet the requirement of integration with the ITER central control system.
