Lesson Plan: X-ray Tubes Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the production of X-rays using an X-ray tube and how the spectrum of X-rays produced can vary.
Students will be able to
- describe the role of the following components/properties/processes associated with X-ray production using a Coolidge tube: hot cathode, target, tube voltage, thermionic emission, and beam current,
- describe the electron energy level transitions in atoms of the target material of a Coolidge tube responsible for the production of characteristic energy X-rays,
- explain how the features present in the X-ray spectrum produced by a Coolidge tube correspond to electron beam characteristics and to target material characteristics.
Students should already be familiar with
- the fact that the kinetic energy of a charged particle due to acceleration through a uniform electric field is ,
- the equation .
Students will not cover
- X-ray absorption,
- X-ray focusing,
- X-ray imaging.
