Abstract: We are building the SOPHI experiment in Saclay, which is a device based on a small 5 MeV electron linac [1] to produce positrons via pair production on a tungsten target. This device should provide 10<superscript>8</superscript> slow e<superscript>+</superscript>/s, i.e. a factor 300 greater than the strongest activity Na<subscript>22</subscript> based setup. The SOPHI system has been finalized at the end of 2006 and the main components have been studied and built during 2007 [2]. The experiment is currently being assembled and first results are expected for autumn 2008. The electron linac, positron beam production and transport system will be presented, and expected positron production rate reported. [ABSTRACT FROM AUTHOR]
