Short description:
The Future Circular Collider (FCC) is a proposed ultra-high luminosity electron-positron collider (also called FCC-ee), serving as Higgs factory, electroweak & top factory, which would be installed in a new 91 km tunnel infrastructure connected to the existing CERN complex. As a potential second step, a hadron collider providing proton-proton collisions at a centre-of-mass energy close to 100 TeV (FCC-hh) could reuse the same tunnel and technical infrastructure.
The FCC-ee was recommended by the 2025/26 Update of the European Strategy for Particle Physics as both the option “A” and (in descoped form) the option “B” for CERN’s next flagship accelerator. The FCC-ee project will be presented to CERN Council for approval in 2028/29, with a possible start of construction by 2032/33. First beams are expected in 2046, and regular physics operation to commence in 2048.

Short description:
The High-Luminosity Large Hadron Collider (HL-LHC) project is a major upgrade to the current Large Hadron Collider. It aims to increase LHC performance and expand the potential for discoveries after 2030. The objective is to increase the integrated luminosity by a factor of 10 beyond the LHC design value.
With the upgrade, the LHC will push the limits of human knowledge and enable physicists to go beyond the Standard Model and its Higgs boson. Following approval of HL-LHC as a priority project in the European Strategy for Particle Physics and approval of its budget by CERN Council, this major upgrade is now in full implementation together with companion upgrade programs for the LHC injectors and detectors.

Location / Institution: Krakow, Poland
Type: Project Upgrade
Short description:
The objective of the project is to design and construct a compact 1.5 GeV linear accelerator at the SOLARIS National Synchrotron Radiation Centre, enabling continuous replenishment of the electron beam current in the storage ring through top-up operation.
The project foresees a hybrid accelerator architecture, partially based on existing infrastructure and complemented by new accelerator sections using C-band technology. This approach will make it possible to reach the target energy of 1.5 GeV in a single-pass configuration within the existing LINAC tunnel, while preserving space for diagnostics, maintenance, and future upgrades.
The upgraded injector will significantly improve beam stability, beam availability, and the quality of experimental data delivered to users. It will also establish the foundation for future applications of the LINAC as a standalone facility, including electron irradiation, accelerator diagnostics and testing, and longer-term development of a free-electron laser and new experimental beamlines.
