  • Using the magnetically driven apparatus CQ-1.5 developed by us, compression isentropes of copper T1, LY12 aluminum, and pure aluminum L1 are measured up to 40 GPa by Doppler pins system (DPS) and Velocity Interferometer System for Any Reflectors (VISAR), respectively. The experimental compression isentropes are compared with the theoratical compression isentropes based on Grneisen equation of state (EOS) and shock Hugoniot data. The results show that the experimental compression isentropes are consistent with the theoretical compression isentropes within a maximum deviation of 3%, and approach to and lie below the shock Hugoniot curves under 40 GPa. The results show that the experimentally measured results are correct and reliable.
