Investigation and diagnostics of plasma flows in a pulsed plasma accelerator for experimental modelling of processes in tokamaks

This paper presents the experimental results on electron, ion temperatures and densities in a pulsed plasma accelerator. The values of electron were computed using methods relative intensities H α β lines, Stark broadening, technique is based Faraday cup beam current measurements. In this work, linear optical spectrometer S-100 was used to acquire emission spectra hydrogen air plasmas. spectrum, there are some lines due Fe, Cu, N 2 , O . series visible atom spectrum named Balmer series. spectral emissions iron copper occur throughout gas breakdown ignition an arc discharge, during erosion sputtering materials. vacuum chamber coaxial electrodes made. accelerator, measured via at charging voltage capacitor bank 3 kV working pressure 40 mTorr, 2.6 eV 1.66 · 10 16 cm −3 for plasma. These compared with However, no match found. Considering analyzing distinction, we concluded that method diagnostics provides more accurate than electrical measurement. theory probe measurements can give approximate moving
