Helium gas is injected into the argon plasma without changing the electron density profile. After the helium gas puff, the dominant fluctuation mode changes from the broadband m = 2 drift wave to the coherent m = 1 mode, where m is the azimuthal mode number. Accordingly, the property of the nonlinear coupling with other fluctuating modes changes from broadband couplings to coherent couplings.}, title = {Impact of helium neutral gas puff on plasma turbulence in linear magnetized argon plasmas}, volume = {27}, year = {2020} }
