2. 21 December 2004NIKHEF 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.
