Abstract
We designed a tool allowing irradiation of large samples over a surface of A5 size dimension by means of a 2.5 MeV Pelletron electron accelerator. in situ electrical measurements (I-V, conductivity, etc.) can also be performed, in the dark or under illumination, to study radiation effects in materials. Irradiations and electrical measurements are achievable over a temperature range from 100 K to 300 K.The setup was initially developed to test real-size triple junction solar cells at low temperature within the framework of the ESA’s JUICE mission. It will be made available to users at the beginning of 2017.After a brief description of the SIRIUS irradiation facility hosted at Laboratoire des Solides Irradies (LSI), this paper gives detailed information about the Large Surface Irradiated-Cell (LSIC) device. Preliminary results obtained during the ongoing qualification phase of the setup are also discussed.
Highlights
Irradiations and electrical measurements are achievable over a temperature range from 100 K to 300 K
The Laboratoire des Solides Irradies (LSI) laboratory at Ecole Polytechnique (Palaiseau, France) is a mixed unit affiliated to CEA, CNRS and Ecole Polytechnique
The SIRIUS facility is equipped with a new generation Pelletron accelerator that delivers monoenergetic electrons beams between 150 keV and 2.5 MeV with a current beam ranging from 150 nA to 200 μA
Summary
The LSI laboratory at Ecole Polytechnique (Palaiseau, France) is a mixed unit affiliated to CEA, CNRS and Ecole Polytechnique. It studies fundamental properties of the solid state and its diverse interactions with radiation (photons, electrons, ions). The laboratory has a 2.5 MeV electron accelerator with the unique feature of having a large variety of in situ characterization techniques. This installation, opened in 2013, is called SIRIUS for Systeme d’IRradiation pour l’Innovation et les Utilisations Scientifiques
