Fundamental objectives and applications

  • The ITFIP team activity covers fundamental and exploratory research, making use of large scale facilities, to perform experimental and theoretical studies of laser-plasma interaction in the strong field regime, and of laser propagation and guiding at ultra-high intensity in plasma media.
  •  The main applications domains are the acceleration of particles to ultra-relativistic energy in under-dense plasmas, the development of new coherent, soft X-ray sources created by short pulse laser and inertial fusion.

Research topics

 

The ITFIP is actively pursuing modelling and experimental studies of electron acceleration driven by laser wakefield in plasmas.  Several key issues for the development of future accelerators are being studied, such as intense laser guiding inside waveguides, the design of new plasma cells,   physical mechanisms for trapping and accelerating electrons in a plasma wave for multi-stage laser plasma accelerators. This work is undertaken in the frame of the electron acceleration scientific programme of  the CILEX project, and contributes to the design of the equipment that will be implemented in the long focal length area of  CILEX. The ITFIP team is involved in the coordination of working groups of the European projects  EUPRAXIA (design study) and ARIES. The ITFIP team uses and contributes to the development of the numerical codes WAKE and WARP. Experiments are performed using French (UHI100) and European  (LLC, Lund Sweden) laser facilities. The ITFIP  team also develops tools for numerical modelling of coherent XUV radiation sources in dense rare gases, in support to experiments performed at the Salle-jaune laser facility of LOA. 

 


Projects

European Plasma Research Accelerator with eXcellence In Applications (EuPRAXIA) project

 The ITFIP group  is strongly involved in the EuPRAXIA project. In addition to contribute to the definition of common parameters and the layout of the facility through simulations, the LPGP will coordinate the design of high-gradient laser plasma accelerator structures.

  The studies undertaken by the ITFIP group are in the frame of several projects and collaboration networks at different levels (regional, national and international), supported by the French National Research Agency (ANR: projects equipex CILEX, ROLEX, ELAHI and COCKER), the RTRA « Triangle de la Physique » (projects APPEAL, ELISA, MULTIPLACCELE) and the European Commission (project EuroLEAP, 2006-2009 and programme « Keep-in-touch » Euratom-CEA on inertial fusion, 2004-2008). The expertise of the group and its scientific production (76 publications in international reviews for 2008-2013) are internationally recognised and ITFIP members have a leading role in these projects especially concerning:

  • The guiding of ultra-high laser intensity in order to create large volumes of plasma with controlled properties, used as X-UV amplifying medium or for electron acceleration,
  • The study of warm dense matter during the interaction with ion beams,
  • The fast-ignition of inertial fusion target.
