2013 Glazebrook Medal

Professor Lyndon Rees Evans, CERN, Geneva and Imperial College London. For his outstanding leadership of the Large Hadron Collider Project.

The success of the LHC is in large measure the result of Lyn Evans’s expertise in accelerator physics and his superb qualities as a project leader. Lyn’s contributions have underwritten many of CERN’s successes in recent decades. His elucidation of performance limitations allowed the CERN Super Proton Synchrotron (SPS) to exceed its design performance by more than an order of magnitude, and was essential for the success of the anti-proton collider that discovered the W and Z bosons. He led the conversion of the SPS into an injector for the Large Electron Positron Collider (LEP), and played a key role in commissioning and developing LEP.

After he was nominated as LHC project leader, Lyn made major modifications and improvements to its design. Under his leadership, the critical components of the LHC, including the most challenging super-conducting magnet system ever built, were produced, installed and commissioned. The result is an outstanding machine which has already exceeded the design luminosity for the energy at which it is operating. Thanks its very high reliability and to the unprecedented luminosity, the Higgs boson was discovered much earlier than was thought possible for a boson with the now known mass.

Lyn’s qualities as a leader were important when the LHC was approved (especially in attracting contributions to the machine from outside Europe) and were essential in the construction phase, when he successfully led a very large team. They have been recognised world-wide by his appointment as leader of the global Linear Collider Collaboration.
