PARIS—Europe’s energy crisis is threatening to slow experiments into the fundamental forces of nature.
The European Organization for Nuclear Research, or CERN, is drafting plans to shut down some of its particle accelerators at periods of peak demand, said Serge Claudet, chair of the center’s energy management panel. CERN is also considering how it could idle the Large Hadron Collider, the world’s largest accelerator, if necessary, Mr. Claudet said.
