Langmuir Wave Study in a Laboratory Plasma – A Model for solar wind}

This is a revised version of the MSc thesis "Langmuir wave study in a laboratory plasma, a model for solar wind" (University of Padua, MSc in Astrophysics and Cosmology). The original is held in the University of Padua repository: https://hdl.handle.net/20.500.12608/94344. Revision, November 2026. No new data or simulations were added. THe text, equations and interpretation were corrected across the following areas: Arithmetic, units and tabulated values, including the Debye length and the similarity-parameter table. A Single convention for the electron thermal velocity, v_th = sqrt(2k_BT_e/m_e), with the Bohm-Gross relation written as omega^2 = omega_pe^2 + (3/2)k^2v_th^2. The Landau-damping estimates, now given with the exact kinetic values for the stated temperatures and wavenumbers. The distinction between the fitted envelope rate Gamma and the linear growth rate gamma of the dispersion relation and a comparisom with the cold0beam estimate (Appendix B.2). The statistical analysis and its reporting, including the narrow operating range of the background-filament data. The description of the numerical set-up, its resolution and limits and the attribution of the Vlasov-Poisson solver (Pezzi et al., 2013), used as provided. Where this version differs from the university copy, this version should be taken as correct. The original copy is held by the University of Padua under a non-exclusive license.
