Experiments with X-rays and visible light teach the basics such as the X-ray Bremsstrahlung spectrum, Bragg reflection and X-ray diffraction. The instructions are developed in such a way that students can carry out all experiments practically completely independently. The students rotate through all three experiments over the course of the day.
Duration: 9-15:30h
Number of students: ideally up to 24, maximum 30
Please bring: pens and calculator
Experiments:
- Measurement of X-ray spectra (Bremsstrahlung and characteristic radiation, cut-off wavelength, measurements possible with different anode materials and crystals)
- Deflection of beta particles in a magnetic field (influence of the magnetic field on electrons and positrons, building principle of an undulator)
- Diffraction images (slits and lattices, determination of lattice constants, insights into X-ray diffraction patterns)
Recommended prior knowledge:
- Diffraction and interference
- Bragg reflection
- Lorentz force
- Radioactive radiation
Additional safety information on the experiments:
Both the X-ray devices and the sealed radioactive sources used are teaching materials specially developed for safe classroom use and each have a type approval. The X-ray devices are fully protective devices and the low activity sealed radioactive sources are designed to prevent any compound release and will be handled only by the Xcool Lab team. If you have any further questions, please do not hesitate to contact us.
There will be more courses on various topics in the future.
