Welcome to research pages for the United Kingdom collaboration at the Free Electron Laser for Infrared eXperiments (FELIX).

The United Kingdom maintains a permanent station at FELIX, directed and operated by two facility scientists. As a consequence of the FOM-EPSRC agreement users from the UK take more than 20% of the total available FELIX beam shifts.

The primary emphasis of the UK programme is the study of dynamic processes, in semiconductor and condensed phase structures, using picosecond mid-infrared and far-infrared pulses.  The main aim of the experiments is to gain a better understanding of the radiative and non-radiative processes that occur during energetic relaxation of carriers in these systems.  This knowledge has applications in the design and technology of mid-infrared emitters and detectors.

The panel on the left can be used to discover who is involved in the project, what we are doing and how we do it.

If you require some information from the old pages they can still be found here.
