摘要
Elementary particle physics is a fascinating field of modern physics investigating the basic constituents of matter and their interactions. In the experiments large accelerators and very sophisticated detector systems are usually used. However, it is desirable to have simple experiments for undergraduate and even secondary school courses which can demonstrate complex investigations in this field. We have constructed a simple setup for the measurement of the lifetime of cosmic muons based on a single scintillation detector. Expensive and complicated professional particle physics equipment for the signal processing, which has mainly prevented the realization of this experiment by non-experts, is replaced by simple, inexpensive and commercially available electronic components. With our setup we register time stamps of the events detected in the scintillation detector and from this data we determine the muon lifetime. Also, a Python software package has been developed for data analysis and presentation of the results.
