Principle
The polychromatic X-radiation from a copper anode is analyzed using a LiF monocrystal according to Bragg. Varying the anode current and anode voltage influences the intensity of the characteristic K a and K b radiation.
Tasks
- Record the intensity spectrum of polychromatic radiation from a X-ray tube with the help of a LiF monocrystal.
- Determine the intensities of the characteristic K a and K b radiations as a function of both, the anode current and the anode voltage, and plot them graphically.
- Compare the results of the measurement with the theoretical intensity formula.
