Separated Antideuteron Beam at IHEP Accelerator

The principle of a method of separation of antideuterons is discussed in this article. The first results on pure antideuteron beam with momentum 12.2 GeV/c for the “Lyudmila” bubble chamber are presented. The intensity of 63 GeV primary proton beam is equal to 1012 per cycle, the mean quantity of \(\bar d \sim 0.7\) per frame with hadronic background ∼30%.
