Recent results of Alfven wave heating in the TCA Tokamak are briefly reviewed. Measurements of the electron temperature and electron density in the TCA scrape-off layer during high power RF heating are presented in detail. It is found that antenna-plasma interaction may lead to a non-Maxwellian edge plasma. Its impact on the interpretation of the edge measurements and the antenna and screen design are discussed.
