Peaked density profiles are measured in the absence of a Ware pinch or a core particle source. Decreasing the plasma triangularity leads to a significant reduction in \u03c7<jats:sub>e<\/jats:sub>. Measurements of the plasma toroidal rotation in the absence of external torque are inconsistent with diffusion of toroidal momentum from the edge. Scrape-off layer fluctuation measurements and the relevant modelling using a fluid turbulence code indicate radial interchange motion of plasma filaments as the cause of cross-field transport. Third harmonic EC heating (1.5\u2009MW) applied to ELMy H-modes leads to \u03b2<jats:sub>N<\/jats:sub>\u223c 2, large ELMs and peaked density profiles, significant ion heating (<jats:italic>T<\/jats:italic><jats:sub>i<\/jats:sub>\u223c 1\u2009keV, with<jats:italic>T<\/jats:italic><jats:sub>i<\/jats:sub>\/<jats:italic>T<\/jats:italic><jats:sub>e<\/jats:sub>\u223c 0.4) and to quasi-stationary ELM-free H-modes lasting for many energy confinement times. Supra-thermal electrons produced during strong EC heating and following sawtooth crashes are shown to undergo rapid cross-field transport. Electron Bernstein wave heating is demonstrated in the O\u2013X\u2013B conversion scheme. Electron internal transport barriers are generated in a variety of scenarios, leading to significant confinement improvement and bootstrap current fractions in excess of 70%.<\/jats:p>","DOI":"10.1088\/0029-5515\/48\/3\/034001","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T04:13:23Z","timestamp":1201148003000},"page":"034001","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Overview of TCV results*"],"prefix":"10.1088","volume":"48","author":[{"given":"A.","family":"Fasoli","sequence":"first","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2008,1,23]]},"reference":[{"key":"crKey-10.1088\/0029-5515\/48\/3\/034001-BIB1","doi-asserted-by":"crossref","first-page":"B277","DOI":"10.1088\/0741-3335\/36\/12B\/023","volume":"36","year":"1994","journal-title":"Plasma Phys.
