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.
