Condensed argon isentropic compression with ultrahigh magnetic field pressure: Experimental design. Post-shot report

摘要

This report continues the series of work devoted to experimental study of a high-dense condensed argon state. What is most interesting and intriguing is the issue of possible argon metallization, when it is compressed up to the densities more than 9.17 g/cu cm. In the experiment of 1995 (the arrangement and data are described in a cited reference) the authors recorded appearance of conductivity in argon, which is non-conductive in the initial state, when it is compressed more than a factor of four. The peak value of argon specific conductivity recorded in this experiment did not exceed 10/(Ohm x cm). This value of conductivity is characteristic of semiconductors, but not metals, which have 10,000/(Ohm x cm). At this stage of the work the main attention is paid to recording of argon conductive state and studying the possibilities of multiframed radiography of the sample in the compressed state.
