High-field magnets (HFM) are among the key technologies that will enable the search for new physics at the energy frontier. Approved projects (HL-LHC) and potential future circular machines such as proton-proton Future Circular Collider (FCC-hh) and Super proton-proton Collider (SppC) require the development of superconducting (SC) magnets that produce fields beyond those attained in the LHC. The programme proposed here will advance beyond the results achieved over the past twenty years in past European and...

CERN Yellow Reports: Monographs, Vol. 1 (2022): European Strategy for Particle Physics - Accelerator R&D Roadmap

European Strategy Update | Laboratory Directors Group Editor: Nicolas Mounet The 2020 update of the European Strategy for Particle Physics emphasised the importance of an intensified and well-coordinated programme of accelerator R&D, supporting the design and delivery of future particle accelerators in a timely, affordable and sustainable way. This report sets out a roadmap for European accelerator R&D for the next five to ten years, covering five topical areas identified in the Strategy update. The...

Bright muon beams and muon colliders

D. Schulte, M. Palmer, T. Arndt, A. Chancé, J.P. Delahaye, A. Faus-Golfe, S. Gilardoni, P. Lebrun, K. Long, E. Métral, N. Pastrone, L. Quettier, T. Raubenheimer, C. Rogers, M. Seidel, D. Stratakis & A. Yamamoto
Muon collider (MC) technology must overcome several significant challenges to reach the maturity of electron-positron colliders. An increased level of R&D effort is justified at the current time, because the muon collider promises an alternative path toward high-energy, high-luminosity lepton collisions that extends beyond the expected reach of linear colliders. The strong suppression of synchrotron radiation compared to electrons allows beam acceleration in rings making efficient use of the RF systems for acceleration. The overall...

The 2020 update of the European Strategy for Particle Physics Update (ESPPU) outlined the current status and prospects in the field, and identified priorities for future particle physics accelerator facilities. In time order, these are: completion and commissioning of the CERN High Luminosity LHC (HL-LHC); a future electron-positron Higgs factory; and a future hadron collider at the highest achievable energy and luminosity.

Energy-recovery linacs

M. Klein, A. Hutton, D. Angal-Kalinin, K. Aulenbacher, A. Bogacz, G. Hoffstaetter, E. Jensen, W. Kaabi, D. Kayran, J. Knobloch, B. Kuske, F. Marhauser, N. Pietralla, O. Tanaka, C. Vaccarezza, N. Vinokurov, P. Williams & F. Zimmermann
Energy Recovery is at the threshold of becoming a key means for the advancement of accelerators. Recycling the kinetic energy of a used beam for accelerating a newly injected beam, i.e. reducing the power consumption, utilising the high injector brightness and dumping at injection energy: these are the key elements of a novel accelerator concept, invented half a century ago. The potential of this technique may be compared with the finest innovations of accelerator technology...

High-gradient plasma and laser accelerators

R. Assmann, E. Gschwendtner, K. Cassou, S. Corde, L. Corner, B. Cros, M. Ferrario, S. Hooker, R. Ischebeck, A. Latina, O. Lundh, P. Muggli, P. Nghiem, J. Osterhoff, T. Raubenheimer, A. Specka, J. Vieira & M. Wing
Novel high-gradient accelerators have demonstrated acceleration of electrons and positrons with electric field strengths of 1 to > 100 GeV/m. This is about 10 to 1000 times higher than achieved in RF-based accelerators, and as such they have the potential to overcome the limitations associated with RF cavities. Plasma-based accelerators have produced multi-GeV bunches with parameters approaching those suitable for a linear collider. A significant reduction in size and, perhaps, cost of future accelerators can...

Sustainability considerations

T. Roser & M. Seidel
Scarcity of resources, along with climate change originating from the excessive exploitation of fossil energy are ever growing concerns for humankind. Particularly, the total electric power consumption of scientific facility operations will become more important as the reliance on fossil fuels is being reduced, carbon-neutral energy sources are still being developed and a larger part of the energy consumption is converted from fossil fuel to electric power. In our accelerator community we need to give...

R&D programmes oriented towards specific future facilities

In summer 2021, the Future Circular Collider Feasibility Study was launched. The FCC-ee builds on 60 years of operating colliding beam storage rings. The design is robust and will provide high luminosity over the desired centre-of-mass energy range from 90 to 365 GeV. The FCC-ee is also the most sustainable of all Higgs and electroweak factory proposals, in that it implies the lowest energy consumption for a given value of total integrated luminosity. In the...

R&D programmes oriented towards specific future facilities

S. Michizono, T. Nakada & S. Stapnes
The International Linear Collider (ILC) is an electron-positron collider with a collision energy of 250 GeV (total length of approximately 20 km). The design study for the ILC for a collision energy of 500 GeV started in 2004, and the technical design report (TDR) was published by the Global Design Effort (GDE) international team in 2013. More than 2 400 researchers have contributed to the TDR. After publication, R&D activities regarding linear colliders were organised...

High-gradient RF structures and systems

S. Bousson, H. Weise, G. Burt, G. Devanz, A. Gallo, F. Gerigk, A. Grudiev, D. Longuevergne, T. Proslier & R. Ruber
Radio frequency (RF) systems are the workhorse of most particle accelerators and achieve high levels of performance and reliability. Despite five decades of improvement the community is still advancing RF performance with several novel developments. The next generation of particle accelerators will likely be still based on RF technology, but will require operational parameters in excess of state of the art, requiring an advanced R&D program. The R&D covers superconducting RF (SRF), normal conducting RF...

• In accordance with the recommendations of the 2020 update of the European Strategy for Particle Physics, the European Laboratory Directors Group has completed a year-long process to determine the status and prospects of particle accelerator R&D in five key areas, and has proposed R&D objectives for the next five-to-ten years with an outline delivery plan to achieve them. The analysis and planning have been conducted by five expert panels, with membership from the European...

The Compact Linear Collider (CLIC) is a multi-TeV high-luminosity linear e+e− collider under development by the CLIC accelerator collaboration. The CLIC accelerator has been optimised for three energy stages at centre-of-mass energies 380 GeV, 1.5 TeV and 3 TeV. Detailed studies of the physics potential and detector for CLIC, and R&D on detector technologies, have been carried out by the CLIC detector and physics (CLICdp) collaboration. CLIC provides excellent sensitivity to Beyond Standard Model physics,...
