ACCELERATE is a Horizon 2020 project, supporting the long-term sustainability of large scale research infrastructures (RIs) through the development of policies and legal and administrative tools for a more effective management and operation of RIs, with a special focus on ERICs and CERIC in particular. To help secure RIs’ sustainability, relevance and effectiveness, the project develops frameworks to improve the offer of tailored services to private and public entities, ensuring outreach to new scientific and industrial communities worldwide and defining common protocols for monitoring and assessing RIs’ socio-economic impact. Finally, a major focus is on capacity building to develop current and future RIs’ staff competences in the field of management, Industrial Liaison and Technology Transfer. The project is carried out while maintaining vigorous communication with research and industrial communities, policy makers, EC administration and other RIs’ stakeholders.
