Time-dependent collisional-radiative model for capillary discharge plasmas

Abstract
A time‐dependent, zero‐dimensional collisional‐radiative model has been developed to study capillary discharge plasmas in view of possibilities for obtaining population inversion leading to laser action in the extreme ultraviolet and soft x‐ray spectral region, by amplifying the Balmer‐α (Hα) line of different hydrogenlike ions with nuclear charges from Z=3 to Z=6. The model is described in detail, and results for the case of a carbon plasma are presented. Limitations of the model are discussed and comparison is made between our calculations and recent experimental results.
