At CERN, we probe the fundamental structure of particles that make up everything around us. We do so using the world's largest and most complex scientific instruments.

Since its construction in 2011, HiRadMat has been a unique experimental facility for testing materials under beam impact
The New Small Wheel system joins the ATLAS experiment after nearly a decade of design and construction
The beam pipe was reinstalled in the LHCb detector over the summer, marking a new milestone in the experiment’s upgrade
The updated version of the ATLAS analysis software will reprocess all ATLAS collision data from Run 2 over the coming months
After over two years of upgrades and maintenance works, the four main LHC experiments are finalising preparations to receive pilot beams
With the upgrade works now over, the experiments in the East Area are taking physics measurements again – time for a rewind
The Laboratory deepens its collaboration with the US-based neutrino experiment with the provision of two enormous stainless-steel vessels for DUNE’s cutting-edge liquid-argon detectors
Calabrese, Capricciosa, Diavola and Margherita – the four modules of the BRIL sub-system – were mounted on the CMS experiment in July 2021
Experiments restart at the Super Proton Synchrotron, CERN’s second-largest accelerator
