The Stockholm Educational Air Shower Array

The primary goal of the Stockholm Educational Air Shower Array (‘SEASA’) project is to bring the intellectual and technical challenge of scientific research to high-school (16 – 18 years old) students. The focus of the project is the high energy cosmic radiation which continually bombards the earth’s atmosphere, generating showers of secondary particles. These showers can be detected by a network of ground-based cosmic ray detector stations. Activity is correlated across the detector network using timing signals from GPS navigation satellites. The detector stations are placed at high-schools and students actively participate in their construction and operation, as well as the subsequent analysis of data. The project illustrates how contemporary research is conducted and offers a modern and concrete focus for student project work in the final year of high-school studies.
