CHART Workshop 2025 for the 10-year anniversary of CHART
Auditorium WHGA/001
PSI, Villigen
CHART (Swiss Accelerator Research and Technology) was founded in 2015 as an umbrella collaboration for accelerator research and technology activities in Switzerland. Present partners in CHART are CERN, PSI, EPFL, ETH-Zurich and the University of Geneva.
The mission of CHART - Collaboration is to support the future oriented accelerator project FCC (Future Circular Collider) at CERN and the development of accelerator concepts beyond the existing technology. CHART projects also exploit synergies with technological developments for synchrotron light sources and medical applications.
The activities are focused on the support of the FCC project and on accelerator development beyond the FCC. High field magnet R&D is one of the main projects, complemented by beam dynamics studies for both FCC-ee and FCC-hh designs as well as FCC-ee injector and positron production test facility. High precision machining and miniaturization are key techniques that will be strengthened. Contacts to industry have been established and will be further expanded in the future. Close collaboration with the main stakeholders from particle physics, but also hadron therapy and the Synchrotron Light Source community is of high priority.
As mentioned above, CHART was founded in 2015 and is therefore celebrating its 10th anniversary this year. On this occasion, we are organising another CHART workshop to give an overview of all CHART projects and to show what has been achieved in the last 10 years.
