Abstract
The LEPTA (Low Energy Particle Toroidal Accumulator) under construction at the Joint Institute of Nuclear Research is described. The goal of this project is to produce a small accumulator for 10-keV positrons with electronic cooling of the circulating positron beam. The main purpose of the accumulator is to generate an intense flux of the electron–positron ground state, so-called positronium. The parameters of the first experiments on a positronium flux and the current status of the work on this project are discussed.
