First results from the Stockholm Educational Air Shower Array (SEASA)

• The 'Stockholm Educational Air Shower Array' (SEASA) project is establishing a network of time-synchronised scintillator detector stations at high-schools in the Stockholm region. High school students are contributing to the construction, installation, testing and running of the detector station placed on the roof of their school. This initiative aims to increase the students' interest in science and technology subjects by exposing them to modem research. Each station is equipped with three plastic scintillator detectors (each 0.3 m(2)) arranged in a triangular formation. Signals from GPS satellites are used to time-synchronise signals from the widely separated detector stations, allowing cosmic ray air showers to be identified and studied. A low-cost and highly scalable data acquisition system has been produced using embedded Linux processors which communicate station trigger and monitoring data to a central database. Air shower data and the performance of each detector station can be visualised in real-time via a web browser. The status of the project is presented along with first results from the observation of air showers over Stockholm.
