Towards a Unified Environmental Monitoring, Control and Data Management System for Irradiation Facilities: the CERN IRRAD Use Case
Résumé
The IRRAD tables are used to remotely control and position samples of different types and shapes in beam. They can move along the transversal beam direction (X, Y) and rotate around it (θ). Shuttle IRRAD-1 The IRRAD1 shuttle is a conveyer moving on a rail and it is used to remotely place small (max. 5×5cm 2) samples from outside to the inside of IRRAD. The qualification of materials, electronic components and equipment for the CERN High Energy Physics experiments and beyond requires testing against possible radiation effects. These quite complex tests are performed by specialized teams working in irradiation facilities such as IRRAD, the CERN Proton Irradiation Facility. Building upon the details of the overall irradiation control, monitoring and logistical systems of IRRAD as a use case, we introduce the motivations for and the general architecture of its new data management framework, currently under development at CERN. This infrastructure is intended to allow for the seamless and comprehensive handling of irradiation experiments in IRRAD and to help manage all aspects of the facility. Its architecture, currently focused on the specific requirements of IRRAD, is intended to be upgraded to a general framework that could be used in other irradiation facilities within the radiation effects community, as well as for other applications.
