Leverhulme International Network

Group Leaders:

The Leverhulme International Network on Femtosecond X-Ray Sources Driven by Plasma Accelerators was established to foster collaboration on this topic between established research groups in (i) the Department of Physics, University of Oxford; (ii) the Max Planck Institute fur Quantenoptik (MPQ), Germany; and (iii) Lawrence Berkeley National Laboratory (LBNL), USA. The network was later expanded to include groups at Deutsches Elektronen-Synchrotron (DESY) and University of Hamburg.

The Network was funded between 1/10/2009and 31/2/2014.
