Abstract: The location of light emission sources in shocked polytetrafluoroethylene is analyzed. It is found that the state of the plate-sample interface has a great effect on the emission profile. Time-correlated pressure and emission profiles and electrical resistance profiles of polytetrafluoroethylene sample were recorded, which allowed the times of the occurrence and the duration of the emission signals to be determined. The emission pulse profile was calculated under some simplifying assumptions on the emittance of the shock-compressed part of the sample. It is shown that, ahead of the shock front, a zone arises in which the resistance of polytetrafluoroethylene decreases by nine to ten orders of magnitude, depending on the state of the interface. It is suggested that a photoconductivity wave induced by the light occurs ahead of the shock front.
Keywords: shock-induced emission, polytetrafluoroethylene, photoconductivity, electrical resistance.
