Delay in Europe Could Mean Extra Year for U.S. Collider

摘要

Physicists were hardly surprised when officials at the European lab CERN announced last week that the world's new highest-energy atom smasher, the Large Hadron Collider (LHC), will not start up in November as planned. Assembly of the $3.8 billion accelerator near Geneva, Switzerland, was more than a month behind, leaving no time for a scheduled month-long "engineering run" before power becomes prohibitively expensive in the winter (Science, 6 April, p. 31).
