Paper Abstract

Small signal gain of H-like, C VI Balmer-α, 182Å line in a Z-pinch plasma is numerically studied to understand the behavior of the gain in the experimental parameter space and to get an optimized condition. A quasi-steady-state atomic code is implemented, which calculates the excited level populations of H-like ion and small signal gain of n = 3 → 2 transition in optically thin case. The developed hydrodynamic code evaluates the dynamics of the Z-pinch carbon plasma. Peak plasma current, Io and initial plasma density, No are changed for a given initial plasma radius, R and the period of plasma current, T. The gain as high as 20cm-1 is obtained for Io = 110kA,No = 2.5 × 1018cm-3,T = 400ns and R = 2.0mm.
