dc.description.abstract© 2020, Springer Science+Business Media, LLC, part of Springer Nature.Gas-filled neutron tubes generating pulses with specified parameters are needed for neutron well-logging. These parameters are affected most by the ion-pulse shape. The results of numerical modeling of the dynamics of the electron beam, secondary ions, and electrons generated in the volume of the Penning ion source with an electron emitter and their effect on the ion-pulse parameters are examined. The calculation was performed in an axisymmetric geometry with the aid of the KARAT software package. The physical processes occurring in the ion source and their influence on the growth of the ion current extracted from the plasma as a function of the maximum current of the injected electrons and the geometry of their source were analyzed. It was found that the steady-state ion current is independent of the electron current and is mostly due to the geometry and radius of the electron beam.
