Spectroscopic determination of electron tenperature in plasma cluster accelerated by a coaxial gun

Electron temperature is determined in accordance with the local thermodynamic equilibrium model and stationary-collisional model. The collisional-radiative model for hydrogen-like ions is extended to all atoms and ions, and a graphic representation of the deviation from the Boltzmann-Saha equilibrium is given. Relaxation processes are discussed and electron temperature 2.6 eV at an electron density 5x1015 cm-3 is determined. (author)
