1. CTDI was reduced and X-ray tube efficiency is improved.

2. X-ray tube is the core component of X-ray machine and has made considerable congress due to constantly emerging of new material and technology.

3. The invention describes an X-ray tube (100) comprising an ion manipulation arrangement (140) having at least one ion collector electrode (141).

4. The X-Ray tube focal spot is obtained by convergence of static field on the electron beams.

5. Rotating around you, the x-ray tube and electronic x-ray detectors are located opposite each other in a ring, called a gantry.

6. This paper introduces a high-volt generator of X-ray tube with low power and high stability for X-ray fluorescence analysis system.

7. X-rays from the anode of the x-ray tube fluoresce an adjoining, independent target that produces a monochromatic spectrum, a portion of which is focused by the x-ray optical system.

8. Objective To study the relationship between x-ray tube potential and patient dose, and to explore the way to reduce the dose.
