Description: In the two years since the last Gordon Conference, we have shifted our interest in laser-plasma interactions to the long pulse (1 ns) regime on the Argus facility. A variable Z disk series (at 3 x 10/sup 14/ W/cm/sup 2/) has been carried out and the Z dependence of line emission, backscatter, /sub h/ (hot electron temperature) and transport inhibition will be described. A variable thickness Au disk series that studied preheat and shocks will be analyzed. A simple theory for why T/sub h/ scales as Z/sup 1/4/ is presented, and a description of an electron transport experiment through layered disk targets is given.
