“…On the one hand, theoretical estimates [24][25][26][27][28] and simulations [29,30] of the conductivity exist and are widely used. On the other hand, experiments have shown order-of-magnitude discrepancies between measurements and calculations [13,19,20]. Predictions of non-Drude conductivities and non-Born collisions have been performed in recent studies [31][32][33][34][35] and await testing with accurate measurements.…”

“…These studies were focused mainly on two general problems: a description of the metal-nonmetal transition occurring in such systems [1][2][3][4] and the dense metallic plasmas characterized by strong interparticle interaction ͑strongly coupled plasmas͒. [5][6][7][8] There is also a practical interest in studying such states of matter caused by some pulse-powered applications, in which a metallic sample is rapidly heated so that due to inertia its density remains relatively high despite a considerable rise in temperature.…”

Thin aluminum foil strips tamped by polished glass plates were rapidly heated by means of a pulse current. The experimental technique has ensured a sufficiently homogeneous heating of the foil samples during continuous expansion from the liquid to gaseous state at a pressure of 7-60 kbar. Results on the electrical resistivity of aluminum were obtained in a density range extending from about the normal solid density down to a density 30 times less and in a temperature range from 6000 to 50 000 K. A dielectriclike dependence of the resistivity on temperature along isochore was observed at a density, which is 4 times less than the normal solid density. A maximum in the temperature dependence of the resistivity was detected along an isochore corresponding to a density that is 5.4 times less than the normal solid density. Present results confirm recent theoretical predictions based on finite-temperature density-functional theory about the behavior of the electrical resistivity of aluminum in the liquid and gaseous state.

“…Pyrometry is however greatly enhanced by the use of an active reflectivity probe to correct for the imperfect blackbody nature of the plasma. 7,10 C. Active probing -VISAR and ASBO VISAR and ASBO are two well established optical diagnostics for monitoring the expansion of a plasma and/or the propagation of a shock through a target. 11,12 If calibrated they can also be used as single-colour reflectivity diagnostics to aid in pyrometry.…”

The ORION laser facility is one of the UK's premier laser facilities which became operational at AWE in 2010. Its primary mission is one of stockpile stewardship, ORION will extend the UK's experimental plasma physics capability to the high temperature, high density regime relevant to Atomic Weapons Establishment's (AWE) program. The ORION laser combines ten laser beams operating in the ns regime with two sub ps short pulse chirped pulse amplification beams. This gives the UK a unique combined long pulse/short pulse laser capability which is not only available to AWE personnel but also gives access to our international partners and visiting UK academia. The ORION laser facility is equipped with a comprehensive suite of some 45 diagnostics covering optical, particle, and x-ray diagnostics all able to image the laser target interaction point. This paper focuses on a small selection of these diagnostics.
