Abstract
For use in a pulsed control system in a logging tool cooperative with a neutron generator, a pulsed ion source power supply is set forth in the preferred and illustrated embodiment. A string of field effect transistors (FET) connected between high voltage supply and ground is connected for switching the output voltage to form pulses of a desired amplitude and frequency. A timing circuit forms off and on control signals applied to pulse forming circuits. Pulse forming circuits form signals applied to gates of the FETs for timed control thereof, controlling the formation of a high voltage pulsed output signal applied to the neutron generator.
