APPLICATIONS OF TECHNOLOGY:
- Oil well logging
- Cargo screening
- Research with neutron sources
- Generates neutrons in similar energy spectrum and yields as radioactive sources
- May yield more energy efficient and compact neutron generators
Radioactive sources are used to examine different parameters of geological formations in borehole logging and soil porosity for oil wells. Replacing radiological sources of neutrons lowers the risk of proliferation, contamination of the environment, and damage to worker health. Researchers at Berkeley Lab have developed ion source and neutron generator technologies yielding neutrons with a similar energy spectrum as radioactive sources. Their approach may lead to a compact neutron source that requires low energy to drive deuterium-deuterium, deuterium-tritium, or tritium-tritium fusion reactions that generate neutrons, replacing radioactive sources in oil exploration applications and others where portability is important.
Berkeley Lab researchers modified conductive nanostructures with catalytic materials to enhance ionic species generation for neutron generators.
The researchers developed a neutron generator including nanostructure electrodes optimized for producing ions.
