Periodic Reporting for period 1 - ARIES (Accelerator Research and Innovation for European Science and Society)

Teaser

Summary

Particle accelerators are engines of discovery for physics, and unique tools contributing to research and applications in health, life sciences, energy, materials, environment. ARIES aims to develop and further improve the European particle accelerators through new concepts and technologies, to provide access to top-class accelerator test infrastructures, enlarge and further integrate the accelerator community, develop a strategy for sustainable accelerator research, and transfer the benefits of accelerator technologies to science and society.

Work performed

The project management has set up the project governance and the collaborative communication tools, defining and promoting the ARIES accelerator R&D community.
The Communication and Outreach Network has carried out activities to improve training, communication and outreach for accelerator science. The project website, intranet, posters, and 15 news articles were prepared, as well as a video with more than 100â€™000 views. An Open Online Course in accelerator science is in preparation, targeted at master level students.
The Network on Accelerator Applications has completed a review of applications of low energy electron beams and related technologies, demonstrating their strong potential impact in material processing, sterilisation, and environment. New applications in the environmental area are being studied, as a new technology to treat marine diesel exhausts with electron beams.
The Network on efficient energy management is studying accelerator subsystems with strong impact on efficiency of accelerator facilities. A first prototype of a novel high-efficiency RF power source has been analysed, and a stand for testing of pulsed beam transport magnets with energy recovery designed.
The Network on Novel Accelerators organized the successful European Advanced Accelerator Concepts Workshop with 300 participants, the main event in a community of more than 50 laboratories and universities worldwide. A special school organized by the Network will take place in 2019.
The Accelerator Performance and Concepts Network organized 16 workshops, covering a large spectrum of accelerator technology, design and operation, in pursuit of raising the technology readiness levels in key areas linked to accelerator performance. The results are already helping improve the performance of modern accelerator facilities for scientific, medical and material-science applications, and the design of future high-energy accelerators.
The ultra-low emittance Network supported recent developments in the synchrotron light accelerator community, by organizing a general and two topical workshops on injection systems and diagnostics. Initial beam experiments have taken place on two test accelerators.
The advanced diagnostics Network contributed to developing beam instrumentation for new accelerator facilities, organizing workshops on non-destructive transverse profile measurements, new profile measurements at light sources, observation of critical parameters at hadron and electron synchrotrons.
The Transnational Access (TA) activities Magnet Testing, Material Testing, Electron and Proton Beam Testing, Radio Frequency Testing and Plasma Beam Testing resulted in a total of 5â€™714 access units (hours) delivered to 129 users. The demand for some facilities was very high, and other facilities delivered access in line with expectations. Some technical problems have prevented a few facilities from operating as planned. Two new advanced facilities are still under commissioning. Although too early for publications, several TA experiments are producing interesting results.
The Promoting Innovation Joint Research Activity (JRA) has awarded 4 Proof-of-Concept grants to support R&D and demonstration of innovative accelerator technologies for applications in environment, manufacturing, material science and diagnostics. Within its industrial tasks, a first batch of hot-pressed MgB2 samples have been produced with additive manufacturing for use in extreme thermal environments. Furthermore, the initial High-Temperature Superconductor cable lengths present the world record for engineering current density at a reduced production cost.
The JRA on superconducting thin film deposition has tested five different techniques of surface polishing and their impact on superconducting film properties, selecting two for further development. New laser based techniques were tested, and the results presented and discussed.
The JRA on production of electron beams for collimation and focusin

Final results

The ARIES Networks have already brought results related to the preparation of alternative future high-energy projects, the definition of common strategies for the upgrade of synchrotron light facilities, and the identification of common instrumentation needs and tools. The Joint Research Activities have exploited and enhanced the complementarities between laboratories, in particular for the common development of new superconducting coatings and of novel materials.
Several ARIES WPs have a strong innovation content, in particular in the fields of high-temperature superconductors, new materials, superconducting coatings, and plasma wakefield acceleration. Breakthroughs in these technologies will have a strong impact on the European accelerator infrastructure, notably as regards the size and cost of future facilities. Furthermore, new innovative accelerator designs have been promoted and supported by ARIES, such as a muon collider design that might constitute an alternative to larger lepton colliders. The Proof-of-Concept projects of ARIES will advance four innovative technologies for societal and industrial applications.
ARIES contributes to the training of young scientists and engineers: the Online Open Course on Accelerator Technology in the advanced preparation phase, the ARIES Workshops attract a wide participation from PhD students and young post-docs, and the Networks have recruited students and post-docs to perform perspective studies.
Joint programming in accelerator S&T is leveraging national funding: some of the ARIES Networks were essential in preparing recent successful proposals at the national level. Some of the ARIES innovations (e.g. marine diesel exhaust cleaning, radioisotope production in hospitals) are expected to have a strong economic impact and are being developed with companies.
