	Surko traps are used successfully, example, for the accumulation of positrons and antiprotons in the experiments on the generation of antihydrogen atoms the ALPHA/CERN. The report presents methods for optimizing the dynamics of the storage of positrons in the Surko trap based on experimental studies on the trap the facility LEPTA/JINR and theoretical estimates of the accumulation and dynamics of particles with technique "Rotating Wall".

	The Low Energy Positron Toroidal Accumulator (LEPTA) at JINR is under commissioning with circulating positron beam. The LEPTA facility is a small positron storage ring equipped with the electron cooling system and positron injector. The maximum positron energy is of 10 keV. The main goal of the project is generation of intensive flux of Positronium (Ps) atoms - the bound state of electron and positron, and setting up experiments on Ps in-flight. The report presents an advance in the project: up-grade of LEPTA ring magnetic system, status of the commissioning of positron transfer channel, the results of the electron cooling system tests, results of low energy positrons storage positron beam formation using Na22 radioactive positron source of radioactivity of 25 mCi.
