Principle

The X-rays that are generated by an X-ray tube are
polychromatic. Numerous experiments (e.g. Debye-Scherrer
experiments concerning crystal structures), however, require
monochromatic X-radiation, which can be generated by filtering the
X-rays with monocrystals or with the aid of metal foils.

Tasks


Record the intensity of the X-rays emitted by the molybdenum
anode as a function of the Bragg angle, using a LiF monocrystal as
analyzer. The energy values of the characteristic molybdenum lines
are to be calculated.

Use the LiF monocrystal to filter out a characteristic line and
record the appertaining monochromatization graphically

Record the intensity of the X-rays emitted by the molybdenum
anode as a function of the Bragg angle, using a LiF monocrystal as
analyzer and a zirconium filter.
