Characterization of a Dynamic Hohlraum used for High-Energy-Density-Physics applications on Z
Abstract
The implosion of cylindrical arrays of tungsten wires in a z pinch is used to form a plasma shell, which upon impacting a low-opacity cylindrical target centered on the pinch z-axis, generates x-rays. The high-atomic-number shell traps a fraction of the x-rays produced within the target, and forms a radially converging hohlraum. Such Dynamic Hohlraums (DH) are being developed on Z as intense sources of x-rays for high-energy-density-physics applications [1]. This paper discusses the measured characteristics of one such DH that is currently in use, which generates a 10-TW x-ray pulse through a 2.4-mm diameter aperture, axially centered, above the target. The characteristics are interpreted using 2D radiation-magnetohydrodynamic-codes and an analytical model [2]. [1] T. W. L. Sanford, et al Phys. Plasmas 7, 4669 (2000). [2] S. A.
