Submitted to AIP Conf. Proc., contribution to the Proceedings of the International Symposium on Exotic Nuclei EXON 2006 (Khanty-Mansiysk, Russia, 2006 July 17th-22nd) - Soumis à AIP conf. Proc. The Institute of Nuclear Physics of Orsay has built in the Tandem building an ISOL device based on photofission induced by a 50-MeV electron-beam~: ALTO (\textbf{A}ccélérateur \textbf{L}inéaire auprès du \textbf{T}andem d'\textbf{O}rsay). The project has been dimensioned to obtain $10^{11}$ fissions/s inside an UC$_x$ target. The objective of this facility is twofold~: ensure the development of the physics with beams at extraction-energy of fission products and to serve as a test bench for certain aspects of the R\&D for the SPIRAL2 project. The first electron beam has been extracted from the LINAC in december 2005 and a UC$_x$-target/ion-source ensemble has been irradiated for the first time in june 2006. The effective yields of the non-refractory fission fragments after extraction and mass separation have been measured during this experiment and are similar to the calculated predictions.
