12/18/2003: Research Associate
Research in the Center for Pulsed-Power-Driven High-Energy-Density Plasma Studies emphasizes the study of high energy density z-pinch plasmas. Most of our plasmas are initiated from exploding fine metal wires, typically = 25 microns in diameter, with currents ranging from 1 kA to a few hundred kA per wire. Two examples are depicted below. On the left is the configuration known as an X pinch, in which the crossing point of the two wires forms an unstable z-pinch that collapses to the axis forming a tiny (~ 1 micron), hot (~1 keV), near solid density plasma. (In the case shown, the wires were molybdenum and the average ionization state of the radiating plasma was about 30.) In addition to studying this unique plasma for its own sake, we also make use of it for point-projection imaging such object plasmas as other X pinches and single exploding wires. An example of the latter is shown below to the right. The exploding tungsten wire clearly shows a mixed (liquid-vapor) phase as a result of plasma formation around the wires before the wires are fully vaporized by a 1 kA current pulse.
We have an immediate opening available for a postdoctoral experimental plasma scientist to work on exploding wire and related high-energy-density plasma experiments. Experience using pulsed power systems for plasma physics research, and/or with exploding wires, is desirable. The successful applicant will have to be able to work independently as well as with small groups from both within and outside of our Center.
Please contact Professor Bruce R. Kusse (607-255-3916; brk2@cornell.edu) or Professor David A. Hammer (607-255-3916; dah5@cornell.edu) for further information and application procedures for this postdoctoral research associate position.
