Experiment nr. 12

High-Resolution Gamma-Spectroscopy with Ge-Semiconductor Detector

Supervisor: Dr. Jürgen Vogt

This experiment gives an introduction to the high-resolution gamma-spectroscopy which is an excellent analysis method for gamma-radiators of arbitrary samples. The verification of the radiation is done with a high-purity Ge-detector. The advantages of such detectors compared to scintillation detectors is the high energy resolution and the high sensitivity which has to be bought by cooling with liquid nitrogen (77K). The experiment gives the opportunity to illustrate the benefits and the problems associated with the final storage and the use of radioactive substances in medicine and technique.

The following exercises are to be solved:
