Shockwave Physics Group

The Shock Wave Physics Group (SWPG) at McGill University is directed by Prof. J. H. S. Lee and has a long history of the study of high-speed turbulent deflagration and detonation phenomena. Current research work includes the initiation of detonation, the transition from deflagration to detonation, detonation propagation in nonideal heterogeneous condensed-phase explosives, and combustion synthesis and dust combustion in microgravity.

The laboratory facilities of the SWPG are comprised of the following individual labs with principal equipment noted:

1. High-speed photographic lab
