“…We applied the above mention diagnostic technique and method to perform the experiments on warm dense H 2 , D 2 , He [33], H 2 +He [26], D 2 +He [32], Ne, Ar [34,35], and Xe [36,37] over several MPa to Mbar pressure region. The two-, four-, six-, and ten-shock in Xe, Ar, Ne, and low-Z gas (H 2 , D 2 , He, H 2 +He, D 2 +He) reverberate back and forth between the two high shock impedance of base-plate and window was directly observed in our experiments.…”
