Advanced Radiation Source Based on Field Emission Electron Gun with Carbon Nanotubes

This study presents the design and characterization of a carbon nanotube (CNT)-based X-ray source. The physical and chemical properties of the directly synthesized CNT were thoroughly examined, and their field emission characteristics were confirmed. Furthermore, the functionality of the fabricated source was validated by acquiring the emitted dose using the digital drive mode at 160 kV. The results indicate that the developed CNT-based X-ray source holds significant promise for potential applications in the field of cell therapy.
