Experimental programmes were aimed at diagnosing and characterizing the core and the edge plasma turbulence in a tokamak in order to investigate correlations between the occurrence of transport barriers, improved confinement, electric fields and electrostatic turbulence using advanced diagnostics with high spatial and temporal resolution. On CASTOR and ISTTOK, electric fields were generated by biasing an electrode inserted into the edge plasma and an improvement of the global particle confinement induced by the electrode positive biasing has been observed. Geodesic acoustic modes were studied using heavy ion beam diagnostics on T-10 and ISTTOK and correlation reflectometry on T-10. ISTTOK is equipped with a gallium jet injector and the technical feasibility of gallium jets interacting with plasmas has been investigated in pulsed and ac operation. The first Joint Experiments have clearly demonstrated that small tokamaks are suitable for broad international cooperation to conduct dedicated joint research programmes. Other activities within the IAEA Coordinated Research Project on Joint Research Using Small Tokamaks are also overviewed. %@group %@group %@group %@group %@group %@group %@group %@group %@group %@group %@group %@group %@group LAP-CTE-INPE-MCT-BR %@group LAP-CTE-INPE-MCT-BR %@group %@group LAP-CTE-INPE-MCT-BR %@secondarymark B1_ASTRONOMIA_/_FÍSICA %@issn 0029-5515 %@affiliation EURATOM/UKAEA Fusion Association %@affiliation Department of Applied Physics, Ghent University %@affiliation Department of Applied Physics, Ghent University %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Institute of Plasma Physics, Association EURATOM %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation KFKI-RMKI, Association EURATOM %@affiliation KFKI-RMKI, Association EURATOM %@affiliation KFKI-RMKI, Association EURATOM %@affiliation KFKI-RMKI, Association EURATOM %@affiliation IAEA, NAPC Physics Section %@affiliation IAEA, NAPC Physics Section %@affiliation Institute of Physics, University of São Paulo %@affiliation Institute of Physics, University of São Paulo %@affiliation Institute of Physics, University of São Paulo %@affiliation EAEA %@affiliation Saint Petersburg State University %@affiliation Saint Petersburg State University %@affiliation Saint Petersburg State University %@affiliation Plasma Physics Lab., University of Saskatchewan %@affiliation Plasma Physics Lab., University of Saskatchewan %@affiliation RRC 'Kurchatov Institute' %@affiliation RRC 'Kurchatov Institute' %@affiliation RRC 'Kurchatov Institute' %@affiliation RRC 'Kurchatov Institute' %@affiliation RRC 'Kurchatov Institute' %@affiliation RRC 'Kurchatov Institute' %@affiliation RRC 'Kurchatov Institute' %@affiliation RRC 'Kurchatov Institute' %@affiliation Islamic Azad University – Mashhad Branch %@affiliation Islamic Azad University – Mashhad Branch %@affiliation CICATA-IPN %@affiliation University Tuiuti Paraná %@affiliation Forschungszentrum, Julich %@affiliation Forschungszentrum, Julich %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation IST %@affiliation ININ %@affiliation Phys-Tech Inst %@affiliation INRNE %@affiliation IAE, NNC %@affiliation ICN, UNAM %@affiliation ITT %@affiliation Association EURATOM-IPPLM %@affiliation Institute of Ionphysics, University of Innsbruck %@affiliation TPU %@affiliation TPU %D 2009 %A Gryaznevich, M., %A Van Oost, G., %A Peleman, P., %A Brotankova, J., %A Dejarnac, R., %A Dufkova, E., %A Duran, I., %A Hron, M., %A Sentkerestiova, J., %A Stöckel, J., %A Weinzettl, V., %A Zajac, J., %A Berni, Luiz Angelo, %A Del Bosco, Edson, %A Ferreira, J.
