Abstract

Measurements of the visible radiation emitted by one dimensional, explosively generated, shock waves in argon initially at 1 atm are reported. A time-resolved spectrograph and calibrated photodetectors were used to measure the intensity of the source at 5450 Å and 4050 Å. The results show that explosive induced shock waves in argon having shock velocities in the range 8–9 mm/μsec radiate at these wavelengths like a blackbody having a temperature of approximately 23,000°K.
