Electron motion numerical simulation results in well-known highly sensitive vacuum gauge of orbitron type at spiral-shuttle particle path with time lapse about 10 ns, axial oscillations period 50 ns, general number of turns about 4000 and path length before 200 m has been shown. On the first step the particle acquires azimuthal component velocity on the way out of local potential well of cathode that prevents its hit for anode. On the second step the electron gets batches of supplementary axial deceleration on intercepting well and reduces the amplitude of axial oscillations. The third step shows significant reducing of spiral radius oscillation amplitude. The aim of the paper is to define physical mechanism operation of optimal orbitron electron trap in ionization gauge.
