“…3.a and 3.b). Due to the configuration it is difficult to separate the positive and negative charges that are located in the vicinity of the interface sample/electrode [5]. Actually, the flux of the 15 and 20 keV electron beam are higher than 100 pA/cm 2 whereas the flux of the 30 keV electron beam is of about 34 pA/cm 2 and despite this large discrepancy the negative charge profile remains in the same order of amplitude as seen in fig.…”

International audienceDielectric materials are frequently used in satellite's structure and especially as thermal blanket which are protecting the electronic devices embarked. Their behavior in relation to an electronic irradiation due to space environment must be clearly defined in order to prevent electrostatic discharges. Such discharges can be very harmful for the equipment. To study these materials an irradiation chamber called `Matspace' has been built in the laboratory. In this study, we will focus our work on the analysis of electron behavior post irradiation in PolyTetraFluoroEthylene films of various thicknesses as they are storing charges for long period of time and they are widely employed in space industry. Space charge distribution will be recorded by mean of two complementary techniques: the Pulsed Electro-Acoustic method and the Focused Laser Intensity Modulated Method

Material used in space aircraft are in contact with a large panel of charged particles. Dielectrics can store charges up to a certain extend above which electrostatic discharges might occur. To prevent these phenomena that can be harmful for the embarked electronic devices, the electrical behavior of those materials under irradiation must be studied. In the present case, we are only interested in the effect of electrons on dielectrics materials properties. To do so, an irradiation chamber has been equipped with various characterization tools to perform measurements in-situ. This work is focused on in situ space charge measurements by Pulse Electro Acoustic (PEA) technique and Laser Intensity Modulated Method (LIMM) during and post-irradiation. Experimental space charge distributions obtained by both techniques will be presented and discussed taking into account the measurement arrangements.

Abstract-Material used is space environment are submitted to a large amount of charged particles. This work is focused on the effect of electrons on PolytetraFluoroEthylene (PTFE) that is commonly found in satellites pieces of equipment. To study the behavior of electrons during and post-irradiation we are mainly using the Pulse Electro Acoustic (PEA) technique in an open configuration. Measurements are performed between two periods of irradiation under vacuum. The space charge profiles obtained are analyzed to understand materials charging phenomena. In the present work we focus our studies on a discharge phenomenon that occurs as soon as the surface potential reaches a threshold value.
