X-ray Diode Measurements of Z-pinch Driven Internal Loads on Z
Abstract
We are pursuing the concept of Z-pinch driven internal targets or 'dynamic' hohlraums for ICF and high energy density physics applications. Utilizing the Z accelerator at Sandia National Laboratories we implode tungsten wires on internal targets at 40 cm/μs with the ultimate goal of generating a high temperature, long lived radiation environment. Nominal parameters for the Z accelerator are a 20 MA peak current with a 100 ns risetime. Wire arrays are configured utilizing 30 and 40 mm diameters, 1-2 cm long with 2.4-2.75 mg/cm. Initial experiments to study the energy coupling, strike physics and the reproducibility of these target configurations have been initiated. Radiation measurements of the off-axis pinch radiation as well as on-axis flux measurements taken with absolutely calibrated x-ray diode arrays will be presented. *Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin company, for the US-DOE under contract DE-AC04- 94AL85000.
