Beam tests boost progress on detector technologies for the Future Circular Collider
The proposed Future Circular Collider (FCC) at CERN would put the Universe under a microscope like never before. By colliding electrons and positrons at four points around a 91 km ring, it would enable scientists to pin down the properties of the Higgs boson and other fundamental particles with a precision beyond the reach of […]
Teams worldwide conducted beam tests on advanced detector technologies for the Future Circular Collider (FCC) at CERN, as the accelerator complex paused for major upgrades. The FCC-ee physics program hinges on the capabilities of the detectors surrounding the collision points. Six concepts are currently under consideration by institutes around the globe.
Much like the LHC detectors, initial beam tests for the FCC-ee commenced many years ago, with the IDEA (International Detector for Electron Accelerator) concept testing muon and drift chamber prototypes using secondary beams from the SPS and PS accelerators in May-August 2026. These tests aimed to evaluate an innovative muon detector prototype with 50-micrometer spatial resolution and a drift chamber employing cluster counting for particle identification.
Additionally, dual-readout calorimeters were tested to determine the energy of particle jets with unprecedented precision. These beam tests marked the culmination of decades of research and development, underscoring tangible progress in FCC detector technology.
