This work is devoted to spectroscopy peculiarities of electric arc discharge plasma with iron vapours. The solution of the main issue of optical emission spectroscopy, namely, selection of iron spectral lines, to study the parameters of non-uniform and non-steady-state plasma source, was considered within this paper. Specifically, the Boltzmann plots technique was used for detailed analysing of application possibility of Fe I spectral lines as well as for determination of plasma temperature. The spatial profiles of selected spectral line emission intensities were used to measure the radial distributions of plasma temperature of free-burning arc discharge between consumable electrodes at 3.5 A.

The Mean

With an image converter camera, developed at the Instituut voor Plasma-Fysica, streak pictures have been made of toroidal θ-pinch discharges in helium at pressures ranging from 0.01 to 0.06 torr. The discharges are produced by a capacitor bank of 2.5 kJ. From the pictures the acceleration of the outward drifting plasma column and the drift time (1 to 2 μs) have been measured. From these quantities the mean plasma temperature after the compression has been determined. The temperature depends on the pressure and varies from about 5 x 105°K at 0.01 torr to 105°K at 0.06 torr. These results are compared with temperatures calculated from the irreversible heating during the compression. From spectroscopical measurements of the intensities of He II λ = 4686 Å and He I λ = 5015 Å the electron temperature is estimated and the assumption of complete ionization is checked.

Good Agreement

The output power and the temperature profile of a copper vapour laser were investigated versus frequency with various kinds of back mirror in its resonator cavity. A semi-experimental method was used for measuring the plasma temperature and obtaining the temperature profile with various back mirrors. The obtained plasma temperature through this method has good agreement with the operational temperature of the laser.

Absorption Studies

Spectroscopic data from a variety of Nd glass laser-irradiated planar targets is examined. The experiments were performed for a number of purposes, including development of intense x-ray sources for absorption studies important in ICF, as well as investigations of target material properties. The data are examined with the non-LTE atomic rate equation code package, RATION. RATION solves for and displays detailed theoretical spectra for a number of H-like, He-like, and Li-like atomic transitions and is presently available to users of the MFE Computer Center network. The package has been enhanced to include a larger number of Li-like levels, some in full detail, and the ability to include time-dependent and space-dependent hydrodynamic information. The main results are spectral line ratios and displays of the full spectrum employing the RATION atomic model. Using these tools, time- and space-dependent plasma temperature and density diagnostics are produced and compared with the experimental data.
