ABSTRACT:
A pulsed neutron generator for well logging is provided having a resistor connected between the anode and cathode. The resistor provides a direct current path whereby corona current can flow between the cathode and a corona point without the necessity for the ion source to conduct. In an alternative embodiment, the secondary coil of a pulsing transformer is connected in series with a resistor between the anode and cathode. In an alternative embodiment, a corona regulator in series with the collector-emitter of a transistor is connected between the cathode and anode of the neutron source and the base drive to the transistor is provided by a light-responsive solar cell activatable by an external lamp. Circuitry is provided for utilizing the various neutron sources.
