What is CHART

CHART (Swiss Accelerator Research and Technology) was founded in 2016 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.

Goals of CHART

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.

The following three lines of main activities have been established:

Applied superconductivity R&D:

The high field magnet R&D on the Canted Cosine Theta (CCT) design and enabling technologies that are being pursued by the CHART Collaboration include both the Low Temperature and High Temperature Superconductor (LTS and HTS) developments. This effort benefits from the synergies with the developments of superconducting magnets for compact proton and ion gantries and the development of advanced synchrotron light sources.

Beam dynamic studies for FCC:

CHART contributed to the FCC Conceptual Design Report published in 2019. A consistent set of parameters based on detailed simulations of beam stability presented in the CDR must be bench marked against the operational data from the present running LHC and against the results of dedicated experiments to be performed at the LHC during the machine development time.

THz laser acceleration:

The activities will be carried out by participating in the high gradient laser acceleration R&D within the Accelerator on the Chip international network. The seed money from SERI is being used to extend the R&D to the THz wavelength range with the aim to demonstrate high gradient acceleration of the SwissFEL electron beam in a prototype dielectric structure.
