Welcome back, Yelong

Dr Yelong Wei

A very warm welcome back to Dr Yelong Wei who re-joined the QUASAR Group as Research Associate.

Yelong first joined the Group in March 2014 as a Marie Curie junior fellow within the LA³NET project at the University of Liverpool. His work focused on the development of a compact, fibre optics-based electron accelerator. Within this project, the coupling of both laser light and electrons beams into different fibre structures was being studied and optimized to maximize acceleration efficiency and enable quantitative measurements for both process. The paper on “Beam quality study for a grating-based dielectric laser-driven accelerator”, authored by Yelong, has been selected as one of the 20 most impactful articles by the journal Physics of Plasmas in 2017.

In 2018, Yelong received a special prize for the best PhD thesis, awarded by the Department's research and impact board.

After successfully defending his PhD thesis, he joined the RF group of CERN as a postdoc fellow from February 2018.  In this role he was responsible for the design of new X-band accelerating structures within the CLIC project including RF modelling as well as RF measurements.

Yelong will be based at CERN and continue working on the development of normal conducting X-band accelerating structures using copper or ceramics.
