21 December NIKHEF jaarvergadering, Ilka Tánczos & Henk Jan Bulten “I have really discovered how beautiful science physics is and I have enjoyed every second of it” Andreas Pantelis H5C

21 December 2004 NIKHEF jaarvergadering, Ilka Tánczos & Henk Jan Bulten2 What is HiSPARC? 1.An experiment to detect high energy cosmic particles and to study their origin. 2.A project to show high schools students a realistic picture of the work at scientific institutes, to stimulate the choice for a scientific study.

21 December 2004 NIKHEF jaarvergadering, Ilka Tánczos & Henk Jan Bulten3 Air showers… (Figure from Nagano en Watson, Rev. Mod. Phys. 72, 689 (2000)). Air showers: highest energies occur rarely (e.g. 1 event per 100 square kilometer per year)

21 December 2004 NIKHEF jaarvergadering, Ilka Tánczos & Henk Jan Bulten4 To detect cosmic showers, a network of detectors is made… GPS …air shower detection
