Testing an Ortec Lifetime System

We report preliminary performance tests of an ORTEC PLS lifetime system based on plastic scintillators and analog electronic system. A variety of samples was measured, from metals (Cu, stainless steel), across semiconductors (Cz-grown silicon, ZnSe) to nanostructured ceramics (ZrO2). All results obtained are compatible with literature reports and indicate the lifetime resolution of the whole system as 180 ps.

Hyper-konstruktywizm w nauczaniu fizyki. Tożsamość indywidualna i kompetencje społeczne

This paper demonstrates how hyper-constructivist methodology used in interactive lectures and workshops in physics for children and young people develops both the individual identity of young people and their social competence. These activities are also examples of the practical implementation of the long-proposed pedagogical contents knowledge.
