Abstract
A well-logging sonde employes a neutron generator. It has a high-voltage supply for the target of the neutron generator tube. The sonde includes an insulated high-voltage conductor for connecting the supply to target, and there is a metallic ring supported on the insulation surrounding the conductor. The ring and conductor form a capacitor that is connected to a circuit for controlling the deenergization of the high-voltage supply if an arc occurs.
