Next Generation of X-ray

Digital Cold Cathode

Traditional X-ray tubes use tungsten filaments that need to be heated to very high temperatures to emit electrons. This method uses a lot of energy, wears out quickly, and requires large cooling systems, which makes the devices difficult to shrink in size. CNT can release electrons at much lower temperatures- a property called field emission. This makes them a good fit for cold cathode technology. However, CNT in powder or paste form was found to be too weak to build reliable cold cathodes. aweXome Ray solved this problem by using CNT in fiber form, and successfully developed cold cathodes that are strong enough for real-world use.

Key Technologies

aweXome Ray’s core technology lies in precisely controlling the structure and properties of CNT to meet the specific needs of diverse industries. We begin by drawing CNT into yarns, weaving them into fibers, and further expanding them into membranes thinner than a human hair. This entire process is made possible by our ability to design CNT structure and tune its properties from the synthesis stage.

  • Cold Cathode Emitter Development

    In 2019, aweXome Ray became the first in the world to develop a high-performance cold cathode X-ray source using pure CNT yarn emitters, demonstrating their readiness for real-world production. These emitters operate by applying high voltage to a carbon nanotube-based cathode, which triggers field emission. This technology supports digital control, enabling low-dose X-ray generation and contributing to the miniaturization of X-ray tubes.

    High-Voltage Control Technology

    Building on high-voltage insulation components and arc suppression design, aweXome Ray has developed the ability to precisely control high-voltage output and fine current levels. This enables the production of high-voltage generators optimized for digital operation using CNT-based electrodes.

  • X-ray Tube Manufacturing Technology

    We manufacture compact ceramic vacuum X-ray tubes by combining CNT-based field emission devices with advanced joining and finishing techniques. These include ceramic-to-metal bonding via ultra-high vacuum brazing, metal-to-metal bonding using laser welding, precision cleaning, and ultra-high vacuum inspection.

Product Type

  • Hard X-ray Generator

    Our imaging X-ray generators operate above 50 kV and are suitable for dental and general medical use, industrial inspection, and security screening systems. These generators are provided as integrated X-ray tubes and high-voltage modules, customized to meet the specific requirements of each customer.

  • Soft X-ray Generator

    Our low-voltage X-ray generators operate at input voltages below 10 kV—including models under 5 kV that are not classified as radiation devices. They are designed for applications such as photoionization, sterilization, and therapeutic medical equipment. Supplied as integrated tube-and-high-voltage units, they are available in both block-type and frame-type module formats to suit various system designs.

  • Block-type module(<5kV)

    This product combines the X-ray tube and power supply into a single compact unit, making it suitable for a wide range of applications. For volume orders, custom configurations are available to meet specific requirements.

  • Frame-type module(<5kV)

    This air-solution-dedicated model consists of an integrated high-voltage ionizer module and one or more collector modules. Depending on application needs, multiple collectors can be combined in a set.
