Abstract :
In this paper we perform exploratory study of short pulses of 14 MeV neutron obtained by laser inertial confinement fusion. We focus on the neutron Radiation-Induced Conductivity (n-RIC) and we show similarities and differences with the classical RIC obtained from photon or charged particles (electron) beams. The n-RIC responses of two insulating linear polymers is experimentally compared: polyethylene (CH2)n and polytetrafluoroethylene (CF2)n.
