Alkali halides are of fundamental interest to the shock wave community, for the number of fundamental phase transformations they exhibit under shock compression and their utility as optical window materials. However, the phase transition from wide band gap insulator into electrical conductor, observed in many insulators under shock and static compression (e.g in diamond [1] and quartz [2]) has been poorly explored for the alkali halides. Meanwhile legacy results of Russian experiments pose a number of unresolved questions such as the possibility of nonequilibrium behavior at Mbar shock pressures.
