Abstract:

The authors have developed a one-dimensional radial fluid code to study the time development and energetics of a Z-pinch embedded in a dense background hydrogen gas. The code uses a flux-corrected Lax-Weindroff algorithm to solve the one-fluid MDH equations together with the external circuit equations in a self-consistent energy - conserving way. Fractional ionization is determined by the Saha equation. Classical thermal and electrical conductivity are included at present, but anomalous transport can easily be inserted if required. Bremsstrahlung emission and absorption is included. MDH instabilities are not included, but are studied analytically in a separate report. Preliminary results indicate that current rise-times at least one order of magnitude faster than the present Pharos circuit about 100 micro sec are highly desirable, and that fusion temperatures do seem possible with these faster circuits.
