Honorary Fellows: Professor Lyndon Rees Evans

For sustained and distinguished contributions to, and leadership in, the design, construction and operation of particle accelerator systems, and in particular the Large Hadron Collider facility.

Professor Lyndon Rees Evans IOP Honorary Fellow 2021

In a long and distinguished career at CERN, Professor Lyndon Rees Evans has made pivotal contributions to the development of state-of the-art particle acceleration and storage ring facilities.

His work has directly contributed to, and fundamentally underpinned, several key advances in particle physics, including the discovery of the W and Z bosons, and more recently, the Higgs boson.

Beginning with the Super Proton Synchrotron (SPS) project, Evans’s work on novel magnet design, and theoretical and experimental studies of stored beam stability, resulted in large intensity increases. He made many contributions to the conversion of the SPS into a unique proton-antiproton collider, which eventually resulted in the W and Z boson advances.

Evans has held a string of leadership roles at CERN, including with large teams at the SPS and Large Electron Positron collider, where he was the division leader. He led the Large Hadron Collider project for 14 years, through all phases of planning and construction of the machine to its eventual deployment in the detection of the Higgs boson.

During this period, he was also a member of the CERN directorate.

Evans has also made major contributions to the development of international facilities in the service of science as a truly global endeavour. He has held positions of responsibility at the HERA particle accelerator at Deutsches Elektronen-Synchrotron and with the Superconducting Super Collider machine.

He has chaired an advisory committee at the Facility for Antiproton and Ion Research in Germany since 2008, and he was a member of a similar committee for the International Linear Collider project.

He was director of the Linear Collider Collaboration (2013-20) and he currently chairs the advisory board for the construction of the European Southern Observatory’s Extremely Large Telescope.
