| Popis: |
The SPHINX machine1 is a 6 MA, 1 μs driver based on the LTD technology, used for Z-pinch experiments. The main loads are cylindrical wire arrays which appear to be, despite the long implosion time of Sphinx driver, efficient plasma radiation sources especially with the use of multi-microsecond prepulse technique. Recently, new configurations have been studied : radial wire arrays to investigate the potential of more compact radiation sources for HEDP purposes and conical wire arrays for laboratory astrophysics experiments on jet propagation. The behaviour of these new configurations with long current rise time have been first investigated on the OEDIPE test bed (730 kA, 1,2 μs) then the scaling up to Sphinx have been done by means of numerical simulations. These MHD codes used to design new configurations and to provide basic physics understandings are MARPLE 2D and GORGON 3D. |
