Separated antideuteron beam at the IHEP accelerator

Problems of application of HF-separators for separation of such rare particles as antideuterons are discussed. The technique is under consideration and first experimental results on separation of antideuteron beam with momentum of 12.2 GeV/c using the 2 m bubble liquid-hydrogen chamber ''Lyudmila'' of the IHEP accelerator are presented. The mean quantity of antideuterons per frame constitutes 0.7 at hadronic background level of approximately 30 % when the proton beam with 63 GeV/c momentum and 1212 part/cycle is extracted on a target. The antideuteron beam characteristics obtained allow to perform a wide program of investigation of (anti dp) and (anti dd) interactions
