Ionization of polarized $3He+$ ions in EBIS trap with slanted electrostatic mirror

Methods of producing the nuclear polarized $3He+$ ions and their ionization to $3He++$ in ion trap of the electron Beam Ion Source (EBIS) are discussed. Computer simulations show that injection and accumulation of $3He+$ ions in the EBIS trap with slanted electrostatic mirror can be very effective for injection times longer than the ion traversal time through the trap.
