On 11 and 12 November 2021, LSC staff gave two laboratory practices for the ‘Master in Physics of the Universe’ of the University of Zaragoza. The first day was a practice with the muon telescope and the second day was devoted to gamma spectrometry with germanium and sodium iodide detectors. It was the first year of implementation of this master’s degree and we can affirm that the sessions were a success both for the students and for the laboratory.
