Ion Traps for Nuclear Decay Studies: a design for a handheld Electron Beam Ion Trap (EBIT)

Nuclear decay studies of ionized species are paramount importance in many astrophysical scenarios: from Big-Bang Nucleosynthesis to cosmochronometer. Recently, new facilities, able investigate nuclear hot plasma, have been conceived and their design is progress. Anyhow, the use plasma ECR traps intrinsically exhibits limitation due high level background and, on other side, necessity push at limit technology get large density temperature. Here we report about a different approach, involving an ultra-compact Electron Beam Ion Trap (m-EBIT) perform for charge-state ions confined cold plasma. A preliminary trap, assembly magnetic field characterization presented.
