SFJCNDT - Model NM -Cold Cathode Carbon Nano X-Ray Tube
Carbon nanotubes (CNTs) are one-dimensional nanomaterials with small sizes and large aspect ratios, which exhibit significant field enhancement effects and can serve as efficient sources of field emission electrons. Due to the geometric enhancement effect, carbon nanotubes are more likely to obtain large field emission currents at low voltages than metals. Carbon nanotubes are highly suitable as cathode materials for X-ray tubes due to their excellent field emission performance.
Our cold cathode X-ray tube uses carbon nanostructures as the cathode electron source, a fixed anode, and a metal ceramic shell. Cold cathode field emission does not require time to heat the filament or rotate the anode, and can be turned on and off as needed, operating at room temperature. Compared to traditional hot cathode ray tubes, it is smaller, lighter, more compact in design, more energy-efficient, and reduces the need for large, heavy-duty generators or battery packs.
