The first summer school organised between University of Barcelona and CERN for secondary students of the Barcelona region took place this year from 2 to 6 July. This event synchronised with the Barcelona Techno Week, a series of meeting point events for top experts in semiconductor radiation detectors and its readout electronics. Fourteen students were selected to take part and benefit from the programme, which included hands-on laboratory work, S’Cool LAB workshops and talks by physicists and engineers in the field of radiation detection and particle physics.
