Abstract
An apparatus and method for in-situ x-ray radiation treatment utilizes different types of miniature energy transducers to emit x-rays. Each type of energy transducer includes a transducer body, a cathode provided at one end of the transducer body, and an anode provided at another end of the transducer body. The transducer body, cathode and anode define a cavity that communicates with an evacuation opening. A desired vacuum is achieved and maintained by a dynamic pumping mechanism that draws a vacuum in the cavity via the evacuation opening.
