From the heart of stars to laboratories, plasmas constitute one of the major objects of the physics in many research institutes. Very big research infrastructures aim at big advances in the understanding of the physics of plasmas. Some Fields of application of science, as inertial confinement fusion experiment or Magnetic confinement fusion for energy, produce very energetics particles that can create nulear fusion reactions. Many of these reactions lead to the creation of very fast neutrons.
Detection of very fast neutrons remains also a challenge for particles accelerators safety diagnostics (beam loss monitor ... ).

We developped a new wide energy neutrons detector able to work in a large gamma background. This concept is based on a very fast electronics associated to a Micromegas detector and a charged to particle converter. The detector can be configurated according to energy spectrum of neutrons, it can sustend very high flux with a good efficency
