In case of a quench in one of the LHC superconducting elements, fast and reliable extraction of the magnetic energy represents an important feature of the protection system. Together with other protection elements, the energy extraction facilities protect the magnets from potentially massive damage. More than 200 energy extraction facilities will be installed for the 13 kA and 600 A electrical circuits of the LHC in order to extract the stored energy of more than 10 GJoule. Concept, design and manufacturing of the system will be discussed. Testing of prototype components will be described. Security, redundancy and radiation issues will be highlighted. The production of the 300 tons of components, their installation in the LHC underground locations as well as operational aspects, such as control and supervision, will also be described.
