a. Electron excitation. A large number of high-speed electrons bombard the sample atoms, resulting in electron transition and X-ray emission.
b. Proton excitation. This kind of excitation method has a short range, but it has strong penetration, which is seldom used.
c. Radioisotopes are used as radiation sources.
d. X-ray tube and x-ray electron accelerator. This is the most common one now. The high-voltage electric field is used to make the high-speed electrons bombard the anode target, resulting in electron transition and primary X-ray emission. Then the primary X-ray is used to irradiate the sample to produce electron transition and emit secondary X-ray. This is a common detection method in the field of industrial analysis and scientific research.
