Development of an Experimental System for Studying Fast Transient Ignition Phenomena

摘要

This paper describes work in progress to develop an experimental system for studying fast transient ignition phenomena. The system integrates several diagnostic techniques to study the fast transient reaction kinetics (approx. 10 mu s temporal resolution) governing the thermal ignition of pyrotechnics and explosives. The principal components of the system include: (1) a time-of-flight (TOF) mass spectrometer and a quadrupole mass spectrometer, (2) a photo-elastic modulator (PEM) ellipsometer, (3) a pulsed dye laser and a continuous wave ND:YAG laser, (4) an infrared detector array, (5) ultra-high vacuum systems, and (6) a high-speed, computer-based data acquisition system. The basic experimental concept is to react samples having a simple, known geometry for which complex heat and mass transfer effects are minimized so that reaction mechanisms and rates can be examined directly.
