Experiments were conducted in order to investigate behaviors of a detonation wave propagating into two pieces of slit, since the detonation wave might be quenched behind a slit-plate by expansion waves generated at a corner of the plate and this technique might be applicable to a detonation arrestor. The detonation wave produced in a stoichiometric mixture of hydrogen and oxygen was propagated through the slits and behaviors of the detonation wave were experimentally investigated by using a technique of pressure measurement, soot track record and high-speed schlieren photography. As a result, when the detonation wave propagated through the slits, it was quenched and a schock wave was decoupled with a reaction front. Two shock waves diffracted from the slits interacted each other at centre of the tube, then this shock wave interaction induced a hot-spot enough to cause local explosions behind the slit-plate. Since the shock wave was reflected from the wall and interacted at centre of the tube, the detonation wave was re-initiated behind the slits.
