New Diagnostics for exploring extreme conditions - laser propagation through turbulent plasmas and power flow at electrodes
Abstract
Collaborations between Cornell University and Imperial College have seen the development of many advanced experimental and simulation techniques for studying the behaviour of materials in extremes of temperature and density. The last 2 years have seen the utilisation of Thomson scattering to provide quantitative data on the temperature, density, ionisation and current flow in plasmas ablating from pulsed power driven targets; the deployment of an imaging refractometer capable of exploring the stability of the flow of ablated material and how the morphology of this flow affects laser propagation; and the production of portable X-pinch X-ray sources to provide radiography and absorption spectrometry of dense plasmas at a targets surface. These have all been supported by new extended MHD simulation capabilities - including the Hall and Nernst terms in MHD - and the introduction of mesh refinement to significantly boost modelling resolutions.
