Radiation spectrum of Z-pinch broadband absorption spectrum source at a 50kA pulse power generator

In order to study the species and density of metastable and excited particles after gas switch discharge, a broadband absorption spectrum source based on Z-pinch plasma is developed. This source consists of a pulse power circuit which generates a pulse current of more than 60 kA and a cylindrical quartz tube where the pulse current drives the gas Z-pinch discharge. At the stagnation time, high temperature and high density plasma is generated on the axis of the cylindrical discharge tube resulting in a intense band board radiation spectrum. In order to study the radiation characteristics of intense and continuous radiation spectrum produced by Z-pinch plasma under different parameters, the axial radiation spectrum at stagnation time is measured with varying driving current and gas parameters (pressure and types). By analyzing these measurements, the optimum parameters are determined to improve the intensity and spectral range of the broadband absorption spectrum source.
