Abstract :
An X-ray tube using CNTs field emitters was successfully fabricated. The high field emission current up to 88mA was maintained steadily by introducing Bi powders to the CNTs paste in the screen-printing process. The dynamical imaging of a living biological sample was obtained using the CNTs X-ray tube under the pulse mode.
