Tubular Electron String Ion Source (TESIS) – improved version of Electron String Ion Source (ESIS) aiming for nearly 200-fold increase in ion yield – is under development at JINR. TESIS advantages over ESIS are discussed and their characteristics are compared. Basic scheme of TESIS operation is presented. One of the crucial processes in TESIS – off-axis ion extraction – requires special confilguration of output electrodes providing steep potential gradient. Numerical simulations of ion extraction trajectories for two different electrode confilgurations are compared and the optimal one is discussed. The obtained results will be useful for TESIS design and construction.
