Time and radial resolved electron density measurement in helium plasma by a double wavelength He-Ne laser
Time and radially resolved electron density in a pinch helium plasma has been measured with laser interferometry. The double wavelength He-Ne laser oscillating at 0.63μm and 3.39μm simultaneously was used. The average electron density via time for the laser traversed portion of plasma was given for different discharge voltage and different helium pressure.
