Abstract

Electrical conductivities of hydrogen and neon were measured during isentropic compression in a magnetic-flux compression device. Hydrogen becomes conducting at a density of about 1.06 g/ ${cm}^{3}$ and a calculated pressure of about 200 GPa (2 Mbar). Neon remained an insulator to an estimated pressure of more than 500 GPa.
