Abstract

This invention provides a reliable, operationally simple means of producing suspension of dust or gas at the end wall of a shock tube prior to the arrival of the incident shock wave. It consists of a cylindrically shaped sample chamber having diaphragms at both ends and a cylinder-and-piston apparatus for driving a powder or other sample from the inside of the chamber into the shock tube.
