CERN's collider to get 'safe' start in November

After a year of setbacks, CERN plans to restart its Large Hadron Collider in November at a tempo that won't overtax the machinery behind the giant particle physics experiment.
The collider, located deep underground on the border between France and Switzerland, will start out running at an energy level of 3.5 trillion electron volts (TeV) per beam, about half the energy that CERN expects eventually. The physicists will inject and capture high-energy beams running in each direction on the circular collider's 17-mile circumference, log data over a number of weeks, and simply get themselves up to speed on the systems.
