In this action, we propose a theoretical investigation of charged particle behavior in external laser fields using the recently-described flying focus" (FF) regime, a laser field setup which allows precise control of the position and velocity of its focus. This novel regime makes it possible to adjust the laser focus so that it co-propagates with the particle, including the situation when the particle is moving against the laser phase fronts. The resulting long laser-particle interaction time enabled by FF pulses is expected to significantly enhance radiation reaction, methods of particle beam control, and cumulative magnetic moment effects along the particle trajectories. In the classical relativistic framework, this will give us the possibility to test the equations of motion, which include radiation-reaction terms and Stern-Gerlach force in the case of particles with spin. In the quantum framework, we will first investigate analytically the probability of single photon emission by a high energy electron in a flying focus beam, and then study numerically the cascade emission of several photons (quantum radiation reaction). Finally, we will implement flying focus fields and the calculated probabilities of the quantum emission processes into the Particle-In-Cell code SMILEI. With this code, we will perform simulations of experimental setups exploiting flying focus fields in laser-particle interactions. Thus we will identify viable experiments that could lead for the first time to unambiguous radiation reaction detection, allow for methods of particle beam control, and enable us to probe quantum electrodynamics in the strong field regime.

PaNOSC will build on top of the existing local meta-data catalogues and data repositories to provide federated services for making data easily Findable, Accessible, Interoperable, and Re-usable (FAIR). Extracting the scientific value of the experimental data produced in our RIs is not always an easy task. The raw data tends to be larger and larger and quite often required special skills for being correctly exploited. PaNOSC will develop and provide data analysis services to overcome these difficulties. The services will include notebook (Jupyter based), remote desktop applications and containers or VMs. These services will be provided locally by the RIs for their users (especially when they are on site or when the volume of data is too huge to be exported), the same services should also be available on the EOSC for general use. The data analysis services will offer in a single user experience the data, the software, the IT capacity and the necessary scientific support. All these services should be fully integrated into the EOSC catalogue, in terms of discovery, accessibility, and user authentication/authorisation, SLA, accounting etc. The PaNOSC cluster will also help introduce a new data culture to the user community – via training at each site and workshops on scientific data management and publishing practices. Best practices in data stewardship will be shared with other laboratories within the PaN community and other clusters. Experiences, trials and results will be shared openly via publications and meetings. The positive experience of implementing an Open Data policy and connecting data and services to the EOSC will help convince other PaN institutes still struggling with adopting the FAIR principles.

CERIC-ERIC (CERIC) is a distributed research infrastructure for fundamental and applied research on novel materials and biomaterials. The RI has been in operation for 2 years and provides open access to a broad range of instruments and expertise across research communities, in order to support the research community world-wide in tackling the most challenging problems of materials research. The ACCELERATE project is proposed to support CERIC sustainability through activities of collaborative development of policies with other research infrastructures (RIs), in particular new and forming ERIC entities. ACCELERATE will assist sustainability, relevance and effectiveness of the RI through preparation of frameworks for services to private and public entities, outreach to new scientific and industrial networks and geographical areas and a methodology for RI social impact assessment. Together with the RI partners CERIC will also carry out several intense courses for development of future RI managerial, IL and TT staff. The project will be carried out while maintaining vigorous communication with research and industrial communities, policy makers, EC administration and other RI stakeholders.

EuPRAXIA is the first European project that develops a dedicated particle accelerator research infrastructure based on novel plasma acceleration concepts and laser technology. It focuses on the development of electron accelerators and underlying technologies, their user communities, and the exploitation of existing accelerator infrastructures in Europe. It was accepted onto the ESFRI roadmap for strategically important research infrastructures in June 2021 as a European priority. To fully exploit the potential of this breakthrough facility, advances are urgently required in plasma and laser R&D, studies into facility design and optimization, along a coordinated push for novel applications. EuPRAXIA-DN is a new MSCA Doctoral Network for a cohort of 10 Fellows between universities, research centers and industry that will carry out an interdisciplinary and cross-sector plasma accelerator research and training program for this new research infrastructure. The network focuses on scientific and technical innovations and on boosting the career prospects of its Fellows.

The FlexRICAN project brings together three landmark ESFRI infrastructures that have, or will have, when in operation different usages of energy: the European Spallation Source ERIC (ESS) in Sweden, the Extreme Light Infrastructure ERIC (ELI), with two running facilities (Czech Republic and Hungary) and the European Magnetic Field Laboratory AISBL (EMFL), with facilities in Grenoble and Nijmegen for DC fields and Dresden and Toulouse for pulsed fields (CNRS, SRU, HZDR). The RIs and partners involved in FlexRICAN will unite their strength to optimize their ongoing (and/or future) energy projects. They will demonstrate that the RIs, as electro-intensive actors, are at the good scale to develop a global energetic approach delivering services to the European electrical grid through optimized energy flexibility and to local heating networks by developing Waste Heat Recovery projects. Developing renewable energy capacity production and managing these developments in an integrated way thanks to energy oriented modelization integrating RIs user communities and the new stakeholders appears like a promising solution. Through the development of a multi-energy approach integrating academic knowledge and two key actors of the energy sector, Alfa Laval (AL) and Energy Pool (EP), FlexRICAN will propose new technologies and solutions to increase resource use efficiency and reduce environmental impacts of European Research Infrastructures (RIs). The project will focus on assessing and validating the implementation of new solutions and technologies at the three ESFRI infrastructures involved. Prototypes and solutions will be developed and tested to identify solutions at the real scale of the infrastructures. It will contribute to quantify energy services and carbon print gain the RIs can performed throughout their full life cycle in order to increase the long-term sustainability of European Research Infrastructures and to contribute to the resilience of the energetical European system.
