Objective
The proposed project has the goal to develop a low energy positron storage ring, based on the radically new principle of the circulating particle beam injection and focusing and methods of slow positron generation. The main application of the proposed ring is the generation of monoenergetic and directed streams of antihydrogen and positronium atoms and performance of experiments with these streams as experimental tests of the CPT-theorem and quantum electrodynamics. The energy of the stored positrons is designed to be varied in the wide range from 10 eV upto 100 keV, which will allow optimum conditions for very different kinds of experiments. Another application of the ring is its use in electron mode (with circulating electron beam instead of positrons) for electron cooling of heavy charged particles (antiprotons, ions) in energy range of the order of 10 - 50 GeV/nucleon. Both applications are of great interest and importance in modern experimental physics. The pliarity of the proposed positron storage ring is the use of electron cooling of positrons to obtain high quality stored positron beam. The electron cooling of positrons is an independent and very important problem in particle beam physics, which is not studied yet experimentally. the general project - design, construction and experimental test of the storage ring in electron mode at electron energy about 10 keV and examination of possibilities for low energy positron generation and setting up of experiments with antihydrogen and positronium in-flight.
