Field-aligned ion beams are often observed in the Plasma Sheet Boundary Layer (PSBL) of the Earth’s magnetotail. Despite their common feature – field-aligned velocity distribution at the lobeward edge of the PSBL, our analysis of Geotail data revealed two different types of ion beams, observed in magnetotail at different times. The first type represents energy collimated ion beams with average observed durations of 4-6 min which for some events may reach 25 min. The majority of such beams have energies . 20 keV. Together with such ion beams, isotropic electron distributions are observed. We suggest that such ion beams are quasi-steady accelerated in spatially localized regions located in a wide vicinity of the distant X-line where magnetic field lines are closed. Another type of PSBL ion distributions represent wide in parallel energy ion beams having energies . tens keV. The registered durations of the most of such beams are less than 3 min. They are observed together with the anisotropic electron velocity distributions formed by the cold and hot counterstreaming components. This feature is peculiar for the magnetic separatrix and indicates that the spacecraft crosses still open or recently closed magnetic field lines. We suggest that such ion beams may be generated by a spatially extended source located near X-line. We have analyzed 987 crossings of the high-latitude edge of PSBL by Geotail at -220 RE < X < -20 RE. The majority of quasi-steady ion beams (Type-I) were accelerated at the interval of distances within -80 - -110 RE and were observed during quiet geomagnetic periods. The second type of ion beams were mostly accelerated within the interval of X ~ -50 – -80 RE , although there was some fraction of events which were accelerated even closer to Earth: between -20 - -50 RE. Type-II ion beams were observed during both quiet and disturbed periods. Energy distribution of the first type of ion beams along the dawn-dusk direction generally confirms the assumption about their non-adiabatic acceleration by the quasi-steady dawn-dusk electric field. Although for high-energy beams of this type the additional acceleration by the weak inductive electric field may also contribute to ion energy gain. On the other hand, energy distribution of the second type of ion beams along the Y direction indicates the presence of ion energization by a strong (presumably inductive) electric field, especially in the case of ions accelerated tailward from the X-line.
