Time-resolved two-band infrared radiometry of carbon tetrachloride under shock compression up to 10 GPa

摘要

Time-resolved two-band infrared radiometers were constructed for measuring temperatures of carbon tetrachloride under shock compression. Radiance histories were observed with about 10 ns time resolution in two slightly overlapping bands, approximately 7-9.5 and 9-12 μm, for shock pressures from 3.3 to 9.4 GPa. The experimentally obtained temperatures (680-1370 K) were consistent with the results of theoretical calculations using equation-of-state data below 7 GPa and suggested the chemical reaction of CCl_(4) at 7.5 GPa.
