The objective of this paper is to explore low-temperature,laboratory plasmas as a benchmark for turbulence simulationcodes originally designed for the edge region of fusion plasmas.Although the plasma parameters are different from those of a fusionplasma, the dimensionless parameters governing the fluid equations forturbulence simulation are similar. Simulations for a wide range ofplasma parameters were carried out to identify relevant quantities whichallow to experimentally distinguish the importance of differentturbulence coupling mechanisms such as parallel resistivity or magnetic curvature.Wavenumber spectra of density and potential fluctuations and theirphases were identified to be relevant for revealing the underlyingphysical processes. Cross-correlations in the drift planegive insight in the microstructure of the turbulence.
