Chellaï, O. Alberti, S. Furno, I. Goodman, T. Maj, O. Merlo, G. Poli, E. Ricci, P. Riva, Fabio Matteo Weber, H. TCV Team 2021 The scattering of millimeter-wave beams from electron density fluctuations and the associated beam broadening are experimentally demonstrated. Using a dedicated setup, instantaneous deflection and (de-)focusing of the beam due to density blobs on the beam path are shown to agree with full-wave simulations. The detected time-averaged wave power transmitted through the turbulent plasma is reproduced by the radiative-transfer model implemented in the WKBeam code, which predicts a ∼50% turbulence-induced broadening of the beam cross-section. The role of core turbulence for the considered geometry is highlighted. application/pdf https://n2t.net/ark:/12658/ffk3336953 https://susi.usi.ch/global/documents/336953 https://susi.usi.ch/documents/336953/files/Paper_for_Nuclear_Fusion_2020(2)-1.pdf eng info:eu-repo/semantics/altIdentifier/issn/0029-5515 info:eu-repo/semantics/altIdentifier/issn/1741-4326 info:eu-repo/semantics/altIdentifier/doi/10.1088/1741-4326/abf43f info:eu-repo/semantics/altIdentifier/ark/12658/ffk3336953 info:eu-repo/semantics/openAccess License undefined Nuclear Fusion. - 2021, vol. 61, no. 6, p. 066011 info:eu-repo/classification/udc/53 Millimeter-wave beam scattering and induced broadening by plasma turbulence in the TCV tokamak http://purl.org/coar/resource_type/c_6501
