Theoretical study of electron-beam-heated carbon plasma C+++ emission

The response of an electron beam heated carbon plasma is studied with particular attention given to Civ(C+++) line emission at 2530 Å which has shown promise in plasma lasing schemes. A theoretical model which follows the plasma's hydrodynamics, ionization dynamics, and beam-plasma interactions is used to identify two distinct plasma responses which depend upon the heating rate. The response's difference is caused by variation of radiated power with plasma temperature and density. The model's predictions qualitatively agree with experimental observations at the University of Michigan.
