The March/April 2026 issue of the CERN Courier is out
A hadron collider’s energy reach is defined by the circumference of its tunnel and the strength of its dipole magnets. Next-generation hadron colliders look set to have tunnels more than three times longer than the LHC. Further expansion of the energy frontier depends on the ability of accelerator physicists to increase the strength of the

The January/February 2026 issue of the CERN Courier is out
Physicists can be allies, wrote Wassily Kandinsky, “who test matter again and again, who tremble before no problem, and who finally cast doubt on that very matter which was yesterday the foundation of everything, so that the whole universe is shaken.” This edition of CERN Courier offers two examples of physics to shake the universe.
