More Information
Summary:A well logging tool includes a neutron generator having a housing, a gas source, a field ionization array, and an extraction ring. The housing defines an ion source chamber, and the gas source delivers ionizable gas to the ion source chamber. The field ionization array directly ionizes the ionizable gas to produce ions in the ion source chamber. The extraction ring produces an ion beam using the ions to initiate a fusion reaction that results in neutron emission from the neutron generator. Additional apparatus, methods, and systems are disclosed.
