Pureron's cold cathode X-ray tube uses an electron source made of carbon nano, manufactured using Pureron's unique CVD film deposition method (patented). This X-ray tube does not require heating of the electron source. This makes it possible to keep power consumption low (it is easy to manage because no X-rays are emitted when the power is turned off).
It can also take pictures instantly and can be used with a power source comparable to that of a dry cell battery.
Due to the advantages of being smaller and lighter, it can be used in a variety of applications such as emergency medical diagnosis, non-destructive testing, and baggage inspection on Shinkansen trains and airports, which require portability.

• 

• No filament power required

  Since heating of the electron source is not required during use, power consumption is low.

• No waiting time

  Irradiation is possible immediately by applying anode to the cold cathode.

• Continuous irradiation possible

  Continuous irradiation with pulsed X-rays is easily possible, making it suitable for video shooting. *Limited to compatible detectors.

• No subfocus occurs

  Images are clearer because there are no secondary focal points.

• high output

  Due to its small size and high output, the device itself can be made smaller and lighter.

• power saving

  It can be used with a power source comparable to a dry cell battery.
