Measurement Of Electron Density And Temperature Using Laser Thomson Scattering In Panta

Electron density (n(e)) and electron temperature (T-e) measurements were performed via the plasma assembly for nonlinear turbulence analysis (PANTA) using the laser Thomson scattering technique. The second harmonic of Nd:YAG laser (lambda = 532 nm) and an intensified charge-coupled device were used as a light source and a detector, respectively. Plasmas in PANTA were generated with Ar gas in a pressure range of 1 - 5 mTorr. The range of the applied magnetic field was 600 - 1500 G. At the center of the plasma, n(e) and T-e ranged (4 - 20) x 10(18) m(-3) and 0.8 - 3 eV, respectively. Further, n(e) monotonically increased and T-e monotonically decreased with the increasing gas pressure and magnetic field. (C) 2017 The Japan Society of Plasma Science and Nuclear Fusion Research
