Comprendre le système climatique de titan avec l'utilisation d'un modèle 3D général de circulation.
Understanding Titan's climate using a 3D model.
Project context
The BTD project was developed in the framework of experiments aiming at the spectroscopy studies of radioactive nuclei using gamma-radiation and light particles in GANIL, mainly with SPIRAL and then SPIRAL2 beams. The purpose of these experiments is to study the structure of exotic nuclei in order to better understand the interactions that bind protons and neutrons and their reactions to different excitation modes (temperature, spin...).
Physics case
The overall picture of particle physics, the so-called Standard Model, has been recently probed by the discovery at CERN of the Higgs particle; it is consistent with the existence of three neutrinos. Oscillations between these neutrinos has been observed in many experiments and are already a compelling evidence of new physics beyond the Standard Model.

Megacam
MegaCam A major instrument at the CFHT observatory (Canada-France-Hawaii Telescope)
The MegaCam camera was developed for the prime focus of the 3.6m diameter Canada-France-Hawaii Telescope (CFHT), on the summit of the Mauna Kea volcano, at an altitude of 4200m on the Big Island of Hawaii (USA).
Objectives:
Megapie (Megawatt pilot experiment) is an international project having as objectives to design, build, test and decomission the first lead-bismuth liquid spallation target functioning under 1 MW deposited power. This target is used as neutron source. Neutrons are produced by the interaction of high intensity proton beam (590 MeV of energy) on the target.
Objectives:
The objective of the Mini-INCA project is to study minor-actinide transmutation processes in high intensity thermal neutron fluxes, in view of proposing solutions to reduce the radiotoxicity of long-lived nuclear wastes. The fission process is the best way to reduce radiotoxicity and also to use the total amount of energy contain within heavy nuclei.

Making high temperature plasmas using laser energy.
Goals of the experiment
The R3B experiment is part of the FAIR project (Facility for Antiproton and Ion Research, http://www.gsi.de/fair) to be built at GSI (Darmstadt, Germany). The FAIR project gathers different physics around a common facility: exotic nuclei at low and high energy, hadronic physics with proton – antiproton collisions, relativistic heavy-ion collisions (a few 10 GeV per nucleon), plasma physics and atomic physics.
