Early Time Spatially and Temporally-Resolved, High-Precision, Thermochemical Measurements Within Detonation Fireballs
Abstract
The proposed research will demonstrate species concentration and temperature measurements inside fireballs of high explosive charges from the 20 gram to 1 kg scale. Tunable diode lasers will be used for water vapor and temperature measurements at 10 kHz applying techniques developed elsewhere into hardened probes capable of withstanding blast pressures and high fireball temperatures. A similar approach will apply our modeless dye laser absorption technology to in-fireball measurements with nanosecond level timing precision. Tests will begin at the 20 gram scale to improve probe durability and pointing stability, followed by tests at the 100 gram scale our large chamber. The final series of tests will be at our field site on charges at the 1 kg scale.
