General goal of the LEPTA (Low Energy Particle Toroidal Accumulator) project, which is under development in JINR now, is to create small positron storage ring equipped with an electron cooling system. Storage ring of LEPTA facility was commissioned in September, 2004. Results of testing the storage ring with electron beam are presented. Positron injector for the ring is based on 22Na radioactive source. Positrons from the source are moderated in the solid neon and stored in electromagnetic trap. First experiments with the solid moderator have been performed. The positron trap is under test now with electron beam. This work is supported by RFBR grant 05-02-16320.

The cryogenic source of low energy positrons based on the 22Na isotope had been designed at JINR. A Solid neon as moderator has allowed to form slow positron beam at energy 1,2 eV and width of the spectrum 1 eV. Such positrons are accumulated after in the Penning-Malmberg trap. Description of the installation and experimental results are presented in this paper. This work is supported by RFBR grant # 05-02-16320
