Abstract
Electron cooling of positrons is the essential peculiarity of the method of antihydrogen and positronium fluxes generation, which is based on low-energy positron storage ring. The design of the positron ring equipped with an electron cooling system is discussed. The positron beam circulates in a longitudinal (quasitoroidal) magnetic field. Electron drift inside special “septum” coils and toroidal sections is used for superposition and separation of the cooling electron beam and the circulating positron one. The working cycle of the ring is described. Peculiarities of the electron cooling of magnetised positrons are discussed. The general parameters of the Low-Energy Positron Toroidal Accumulator (LEPTA), which is under construction in the JINR, are presented.
