The biometric control to access the LHC is being set up. An iris recognition system will ensure the security of the entrances to the accelerator with special vestibules.

A complete LHC sector 3.3 km-long and cooled at –271°C is powered up for the first time.

Several thousands of amps circulate in the superconducting magnets installed in the tunnel. Members of the groups involved celebrated with champagne.

Frédérick Bordry, leader of the Power Converter Group, and Roberto Saban, responsible for coordinating the LHC commissioning, celebrate the end of the first powering-up of an entire LHC sector

The electromagnetic calorimeter barrel receives its thirty-sixth and final supermodule.

CMS installs the last of its 36 supermodules for the barrel of its electromagnetic calorimeter.

More than 60 000 lead-tungstate crystals, transparent like glass but heavier than iron, form the subdetector of the experiment.
