Monochromatisation of copper X-rays



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 ...

Duane-Hunt displacement law and Planck's "quantum of action"

Principle

X-ray spectra are recorded as a function of the anode voltage. The short wavelength limit of the bremsspectrum is used to determine the agreement with the Duane-Hunt displacement law, and to determine Planck's "quantum of action".

Tasks

  1. Record the intensity of the X-rays ...

Absorption of X-rays

Principle

The polychromatic X-radiation that is emitted by an X-ray tube is filtered in terms of its energy with the aid of a monocrystal. The resulting monochromatic radiation is used as the primary radiation source for examining the absorption behaviour of various metal foils of ...
