ABSTRACT OF THE DISCLOSURE A neutron accelerator tube for radioactive well logging has a target section, a replenisher section and an ionization sec- tion located between the target and replenisher sections. A novel form of ionization section is provided which includes an ionization chamber adapted to receive accelerator gas from the replenisher section and spaced cathodes having opposed active surfaces exposed to the interior of the ionization chamber. In addition, an anode is located intermediate the cathodes whereby, in response to an applied positive voltage, electrons created by field emission are transmitted between the opposed active sur- faces of the cathodes and produce secondary electrons upon im- pacting an active cathode surface. The active surface of at least one of the cathodes is formulated of a material having a secondary electron emission factor of at least two.
