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.

BETACOOL program developed by JINR electron cooling group is a kit of algorithms based on common format of input and output files. The program is oriented to simulation of the ion beam dynamics in a storage ring in presence of cooling and heating effects. The version presented in this report includes three basic algorithms: simulation of r.m.s. parameters of the ion distribution function evolution in time, simulation of the distribution function evolution using Monte-Carlo method and tracking algorithm based on molecular dynamics technique. General processes to be investigated with the program are intrabeam scattering in the ion beam, electron cooling, interaction with residual gas and internal target.
