CERN's Large Hadron Collider enters four-year upgrade period.

CERN's Large Hadron Collider (LHC) has begun Long Shutdown 3 (LS3), a four-year period for its transformation into the High-Luminosity LHC (HL-LHC). This upgrade aims to increase the collider's luminosity tenfold, allowing researchers to gather significantly more data for future scientific exploration. While particle beams are paused, data analysis and preparation for enhanced operations will continue.
