Abstract	Summary form only given. It was shown in the previous publication (Semyonov, 1999) that the high-energy electrons of the Maxwellian distribution tail inside the Bennett pinch with axial inductive electric field drift toward z-axis and form the axisymmetric trajectories oscillating in radial direction and drifting in negative-z direction (to the anode) (modified run-away). Computer simulation of high-energy (in relation to plasma temperature) electron movement inside the pinch with non-skinned current (magnetic distribution was approximated by linear dependence on radius) is performed here. Electron trajectories for different initial conditions and energies were calculated. 3D trajectories look like the flattened spirals precessing with time for the electrons born near z-axis and like deformed spirals for the electrons born near micropinch edge. Commonly, first two or four axisymmetric revolutions reveal that the period of time when radial projection of velocity v/sub r/ exceeds the axial projection v/sub z/ is more then for opposite relation, but three or four revolutions are enough to escape from micropinch. Statistically at any given moment a number of electrons moving chiefly in radial direction exceeds the amount of electrons with v/sub z/>v/sub r/ resulting in experimentally observed polarization of X-ray lines. Energy loss from micropinch plasma is estimated and the role of modified run-away in energy balance is discussed.
