On 9 May 2017, CERN will be inaugurating its new linear accelerator, Linac4. This new 90 m long machine sits 12 metres below the ground and took nearly 10 years to build. Linac4 is an integral part of the programme aimed at modernising CERN’s accelerator complex for the needs of the High-Luminosity LHC project. It is destined to become the first link in the LHC injection chain, enabling the LHC to deliver more intense beams to the experiments. The luminosity of the LHC is scheduled to be increased by a factor of 10 by 2025, which will bring about an increase in the number of collisions and thus in the volume of data recorded by the experiments. The High-Luminosity LHC will provide researchers with more accurate measurements of fundamental particles than is the case today, as well as glimpses of rare processes that occur beyond the machine’s present sensitivity level.

The ceremony will take place on CERN’s main site in Meyrin. Guided tours of the new linear accelerator, Linac4, will be organised beforehand.
