Charge Build-Up and Transport in Electron Beam Irradiated Polymers in a New Irradiation Chamber
Résumé
In order to study the behavior of dielectric materials under an electronic bombardment, a new irradiation chamber has been designed and lately constructed in the laboratory. In a near future, this chamber will be equipped with various experimental set-up allowing measurements in-situ. The aim is to combine complementary information to get a better knowledge on charge transport, storage and release in insulating materials in relation to the electron beam energy and flux. In this paper, we briefly describe the irradiation chamber, and we present our first results obtained by Pulse Electro-Acoustic (PEA) method and by Focussed Laser Intensity Modulated Method (FLIMM) on Polytetrafluoroethylene (PTFE) films after irradiation under a low energetic electron beam.
